Nothing wrong with the MRM cat

,
It's a really fun mech to use in SA mode, especially when the assaults roll around. When it runs out of missiles this thing is just a slow bag of free points, and it can run out quite fast (roughly 12 volleys per bank if you use your 2 tons for MRM ammo).
I've been caught with my pants down many a time in this, and it's a real mission to get to the repair pad for reloads.
Part of the reason everyone just shoots the first target is that most people can't actually identify the leaders in combat, unless you remember their handles. Maybe if the target display also read out the leaderboard position of the enemy (i.e. 1st, 2nd, 3rd). This would encourage more head hunting.
