Second is a series of quirk adjustments that will emphasise the lines between the Mech classes. First in line will be the Medium Mechs with a series of agility buffs coming their way.
So lets start at what they suggested, with agility.
Okay, the first thing that comes to my mind is slopes. Fast and "agile" mechs like the Quickdraw, Dragon, Cicada, and others move up hills as a greater rate than other mechs.
Yet we get mechs like the Cataphract, not exactly renowned for its agility, at least not the base chassis, and it is in the same level as those other mechs. Perhaps we can make mediums stronger in comparison by reducing the climbing power of those other mechs?
Now that's not a whole lot. Lets also take a look at other alternatives. We could allow medium mechs to have their torso twist more greatly affected (in a positive way) by engine sizes. This means that even with a base 200 engine, the hunchback might torso twist faster than before.
Another huge issues is obviously one of scaling. Unfortunately, this is the least likely issue to be altered due to the difficulty of doing so, as mentioned by the devs themselves in Ask the Devs #42:
While I disagree heavily with their assessment about sizes and densities (there are a million threads discussing why these scales aren't up to snuff), and while I also don't want that sort of discussion to consume this thread, its clear that scaling heavies properly, and scaling a few mediums better (particularly the Trebuchet) would help them out by making heavy mechs a less obvious choice, and making mediums a bit harder to hit.
On a different note, weapon buffs can help mediums out. Most mediums take weapons weighing less than 3 or so tons a piece. Medium lasers, medium pulse lasers, and SRMs are the name of the game. With medium pulse lasers being in the state they're in, buffs would help some mediums out. Buffing the LBX would also help, as it is a lighter autocannon but is supposed to pack a punch.
In terms of medium strength, I'd say the current rating is something like this:
Centurions = Blackjack > Hunchbacks = Cicada > Trebuchet
Trebuchet's largest issue is that it is a tall mech, and thus an easier target. Hunchback's are actually quite compact and have good loadouts, but don't pack the same punch as a Centurion, and if they do, they suffer from being an 4G, 4H, or 4P and having their classic hunch. Cicada's aren't bad, but they aren't great either, considering for 5 tons less you get the same number of energy points but on a smaller, harder to hit mech with jump jets. Blackjacks are great and honestly pretty nice little mechs. For 45 tons they're very compact mechs, and have great loadouts. Centurions are very strong because you can either take the D for speed, or the A for firepower (of which there is a lot thanks to the SRM buff). Centurions also have one of the most powerful hitboxes (or awful, if you look at it like that) in the medium class, and are absolute damage tanks (unless you go for the legs, which are typically under armored and easier targets).
So lets help PGI out with this one. What things can be done to help mediums out, particularly in the realm of agility?
