The 3 new classes they added are kinda trash IMO.
Vorcha is cool but relies too much on constant killing to maintain it's HP regen. Plus it has the durability of wet paper so it's almost impossible not to die while you look for things to constantly kill. They should've given it damage reduction like Sentinel, or a lot more HP and Shields.
Quarians are cool but not as cool as the other races that already have those jobs.
Cerberus Vanguard and Adept would be cool, but the animation on Smash is too damn long....on Silver or Gold most of the time you'll die before the animation even finishes. Also on Adept, Lash + Smash should make a Biotic combo....but it doesn't. Which makes no sense gameplay-wise.
The 3 new weapons are beastly though. The Krysae Sniper Rifle is arguably the best Sniper Rifle in the game, the Cerberus Harrier is retarded powerful and the Reegar Carbine is the best Shotgun. Also the new maps are cool too.
