If you are a Light, call the target into VOIP so everyone knows what's out there, chase them, and then shoot them anywhere. Legs are helpful, arms are too. Don't engage at close-range. If you have other Lights with you, this will definitely discourage the Lynx. If someone on your team calls out they they've spotted one of these Lynxes, go protect your heavier lances and remind them to use the Buddy System until you get there. Flamers will keep the Lynx from using its laser weapons (remember jump jets can be hot) which may prolong your components being opened up.
If you are a Medium, call the target into VOIP so everyone knows what's out there, and then engage at range. Don't get close unless you have lots of streaks and armor or really good accuracy. Flamers will keep the Lynx from using its laser weapons (remember jump jets can be hot) which may prolong your components being opened up. Lights are on their way to help. If you have other Mediums with you and can't run away, distance yourselves in such a way that one of you can always be shooting the Lynx, no matter how much it dances (say, 150-200m at most). You can also stand back-to-back. If you have any doubts, run away together (in a way that keeps the slower of you from falling behind). If you are equipped and confident that you can handle an MG Lynx and hear the call over VOIP, go protect your heavier lances and remind them to use the Buddy System until you get there.
If you are a Heavy, call the target into VOIP so everyone knows what's out there, back up to a wall if you can, pop a UAV, and try to spread the damage as much as possible across all your armor. If you've got streaks or flamers, use them now - flamers will keep the Lynx from using its laser weapons which may prolong your components being opened up. If you have other Heavies with you and can't run away, distance yourselves in such a way that one of you can always be shooting the Lynx, no matter how much it dances (say, 150-200m at most). You can also stand back-to-back. If you have any doubts, run away together (in a way that keeps the slower of you from falling behind). If you've got decent armor and want to drop a strike on yourself, go for it - smoke usually scares them off. Help is on the way.
If you are an Assault, call the target into VOIP so everyone knows what's out there, back up to a wall if you can, pop a UAV, and try to spread the damage as much as possible across all your armor. If you've got streaks or flamers, use them now - flamers will keep the Lynx from using its laser weapons which may prolong your components being opened up. If you've got decent armor and want to drop a strike on yourself, go for it - smoke usually scares them off. You can also stand back-to-back. Smoke will scare them. Help is on the way.
If you are in an MLX-G, call the target into VOIP so everyone knows what's out there and enjoy the duel.

Notes: Don't waste ammo you know can't hit with - Lynxes want to deplete your ammo. Don't think you can handle this alone - you probably can't (because if you can, the Lynx will run away as soon as it sees your loadout). Don't ignore the Lynx you just saw 800m away jumping between buildings until he's ripping into your back - call the target out, spot it if possible, and specifically mention what you saw and encourage Alpha Lance to stay close. Not to pursue (unless they, too, are MG builds looking for a duel) - Lynxes are tricky like that, pulling Alpha Lance away and then gunning for the bigger targets - but to be aware and ready to support on a moment's notice. Their arms are squishy, their legs are squishy, their CT is kinda squishy too - any concentrated fire, or the potential of it, will likely scare them off. Yes, they will eventually get desperate. That's okay. They'll hurl themselves at your Charlie Lance in desperation for glory. They want your attention, so make sure you have the proper support and don't have to stop firing at the bigger Reds.
There's nothing 100% predictable about a good Lynx pilot, no matter the build. These are just guidelines to help. The best counter to the MLX-G is to discourage it until it loses patience and makes a mistake or finds itself vastly outnumbered. Being outnumbered in early/mid-game means you've been sticking together. If you find yourself alone for any reason and then die to a thousand rounds of machine gun fire coming from all directions at once, don't blame the Mist Lynx. What were you doing alone in the first place?
Boating is a thing that happens. This isn't primarily a lore-based game. If we are given the chance to build an optimal loadout and that loadout includes bringing multiples of the same weapon for the sake of ammo efficiency, it's neither illegal nor poor form to do it - and it shouldn't be treated with disdain or surprise by other players. Other factors are supposed to keep skilled players from the lesser-skilled players but that doesn't always happen. The Meta shifts (in theory) to accommodate new changes to the game and this is one of them. Pilots who've been in Lynxes for years will excel in the MLX-G, new pilots will still probably do alright. It's just the way it is. Shoot them. Shoot them and chase them away and don't give them the satisfaction of finding a lone Heavy with dual gauss and some small lasers who sacrificed armor for ammo.
The MLX-G is also a thing that happened (I suspect PGI wanted to see what MG boats did before releasing the Piranha - and those will be pretty easy to counter as well). It's neither over-powered nor Easy Mode. It dies easily and thrives on what appears to be the normal habit of a lot of its victims - poor communication and coordination with team, lone wolf behavior, and builds that have poor point defense. QuickPlay is a veritable playground for disorganization, Rubellite even moreso. Of course it's not always that... but it's that a lot of the time. Minimize the chance that it happens to you by following the above advice.
This isn't difficult. It's not an OP 'mech, it's not that MGs are suddenly OP (if eight machine guns are pouring into your open component, it's not the crits that are killing you), it's literally that boating the MGs has now become a thing that a couple 'mechs do well - and they are very easily countered. It doesn't always work but don't lose heart and give in to the Saltier Side - that's exactly what they... what we... want.
