I've really been enjoying the blitzer against the bugs. Never have to worry about stalkers because it stuns them and never runs out of ammo, and it kills medium enemies really efficiently.
I use the plasma punisher against the bots as well since it stuns devastators and is perfect for small groups of troops and walkers.
Definitely the best warbond after the launch one
stun grenade is in there too
I think it'd be cool to have locations on maps you could put requisition points into to get rewards etc, kind of like the friendship bunkers
