You are legging to kill mechs, which is why this entire thread and my one exsist. You shouldn't be shooting at someones leg on purpose to kill them, you should be shooting their leg to slow them down.. The very fact snipers and LRM boats don't move means shooting at their CT is FAR FAR easier, and quicker/more score/a kill than legging them. Not to mention most snipers and LRM boat's hide their legs.
Legging lighter mechs to slow down them would be a waste of time, however. For starters, their legs are moving all over the place, the legs have the same armor/slightly less than their CT, and the CT is a much bigger target that always faces you when they're shooting you; you can simply blast their face off and be done with it, rather than somehow shoot one of their leg's armor off without them noticing, then shooting them in the face.
I don't see how you people complain about legging so much; I only get legged when I ride around ontop of another mech in a Hollander, or when I'm spamming SSRMs in the Vulture. If I see someone aiming for my legs, I do this amazing, revolutionary tactic called "turn around your legs and blast their gun off"
When I
do get legged, I power down and wait for some poor shmuck to run up to finish me off, power up, then I fire all my guns and bail, then go for
their legs or BT with my AC/2.
