LRMs are annoying, and I severely dislike the way PGI made it so easy to deliver indirect fire (which should also be way more inaccurate)... but that in itself doesn't make the weapon system effective. I don't think I've died even once to LRMs on Highlands- I've
seen lots of them, but avoiding them really is as easy as "get into trench, turn 90 degrees, run along trench." If you're still taking missile fire after that, then find the spotter-
quickly- because they're likely very close if they can see you inside the trench. Shoot the spotter, stop the missiles. Are you hurt? Yeah, but not any worse than you would be if you got the bad end of a direct-fire trade.
Seriously, though, they're not that dangerous. They're the least efficient weapons in the game on a damage-per-ton basis, because of both damage spreading and missed shots due to loss of lock or hard cover between shooter and target. They have a huge dead zone which puts LRM-dependent builds at a crippling disadvantage against... well,
anything that can close the distance and engage at less than 180m. They take a significant amount of time to kill even a light 'Mech, you get an audio/visual warning splash in your cockpit when the enemy fires them at you, and because they take so long to reach their targets you have
ages to break LOS and avoid at least most of the incoming ordinance. If you can't do that, then you're badly out of position, and would have likely met a gruesome end sooner rather than later anyway the moment someone with a more powerful direct-fire config drew a bead on you.
Full disclosure: I don't have modules on most of my 'Mechs. I own
two Radar Deprivation modules and about
90 'Mechs, and I don't always remember which chassis I left them on, let alone to move them to the one I'm
using at any given time. I hardly ever drive my ECM 'Mechs, and I think I have a grand total of two 'Mechs with AMS. If LRMs were OP, they should be my #1 cause of death, but I think they get me maybe once every other week... and it's
always my own fault. Got impatient or overconfident and went somewhere I shouldn't have. Let myself get surrounded and the missiles just
happened to get the killshot amid five other damage sources chewing my bits off. That kind of thing. No big deal... thirty seconds or so of a lot of loud and colorful language directed at the monitor, a quick facepalm, then I grab another beer and try not to do the same dumb thing twice in a row. It doesn't take being a 1337 meta tryhard to avoid messy missile massacres... hell, I freely admit I'm a potato and the only reason my PSR increases at all is because it's basically an XP bar. If I can manage to stay out of the rain most of the time, you can too.
It's hard to admit error, but you really should not be dying frequently to LRMs unless you are doing something seriously wrong. Be it your positioning, or how you react when you take LRM fire, there's a cause to be found somewhere and you will have a much better time of it once you figure out what that cause is. If it is too difficult to pin down where the problem is in the chaos of the moment, then I'd recommend recording your matches and watching the ones where LRMs kill you later on, after you've cooled off a bit. There's no reason why you can't learn to evade and break locks...
...so that you can move on to complaining about OP
laservomit like the rest of us do.
