There are many different class combinations to use on blitz. So tell me what are yours? Mine are mostly the support and assassult but now my friend is choosing the tank so support+tank! And if you play alone tell me what class do you use?
Alone? Tank. In teams, though, a Tank/Support combo is likely the best way to go. I got to round 79, I think, with awful randoms because we had 2 Supports who were great at keeping turrets hacked, but awful at purchasing them and keeping desperate Tanks healed, and another random and myself as Tanks, the other Tank completely unaware as to how to Death Blossom (he used the railgun for most of the match, switching to Jet Gun's POWERFUL SINGLE STREAM for crowd control). And we still got to round 79 before I ran out of money for purchasing turrets. Not a bad handicap run, I must say, and it was thanks to the classes we played. Still trying to figure out what the best turret placement is, though.
Any combination of Supports and Tanks. Three tanks can Deathblossom anything that comes out of the doors and take care of Jackbots, whereas the Supports can take out the stragglers and hack the necessary turrents. Each Supports can keep 4 turrents hacked in the center, which can prove useful, especially when you run multiple Supports.
