"A class system is in place where you can set distinct weapon load-outs to include suit upgrades (perks). Weapon sets are a thing of the past. We've added a sprint button. Teammates can be revived. In addition to the level rank and ELO matchmaking systems, we have an additional currency system that lets you purchase upgrades, be they weapon and suit upgrades, or different armor pieces to customize your character's look."
Looks like TCON2 won't have weapon sets, but you can choose your own weapons.
