There's a point realism needs to be sacrificed for the sake of the game. Mechs won't exist in real life, doesn't matter how much armour you give the centre torso if you can just shoot it in the foot and it falls over!!!
If your leg gets destroyed it should make you limp, 2 legs gone and your useless. 1 heavy guass shot atm and you light mech is useless! If it were 2 then you might as well shoot them centre torso and kill them!
The other day I had the best game I've played, it was awesome, me and sheepy ended up starting with 250k cash on respawn... We had 10 kills 1 death each, I head shotted someone's driver and stole a novacat after I lost my atlas and carried on raining the pain on the enemy pushed back inside their own base. Game crashed, I decided to switch teams when I rejoined because most of our prey had left and it needed balancing... So out comes an Atlas, I spread my remaining cash around and we push them back and fight continues in the open. This was great and proved how good this game really can be.
But then today the servers were empty except for lagging american servers so we played 1 v 1, Sheepy got the first kill... By legging my mech... So he came back with a hollander... 1 shot legs me again... I partly blame sheepy for not having the guts to fight properly

but really atm the game is set up for this, get in hollander, 1 hit light mech leg, kill ba, repeat...
Everyone says L2P (learn to play)... Well atm it should be L2L (learn to leg).
