No. It's easy enough to just do that as it is, and it goes against the entire premise of this game. Some classes are designed far more to work with the stage than players.
The classes aren't balanced for Deathmatch. There are plenty of shooters out there that offer TD why not play those for your fix.
One of the devs said they wouldn't introduce a game mode without bots or turrets because it is what defines the game. Or something.
i think they could get creative enough to build a TDM that may involve bots and such. and to say that the classes arent balanced for killing isnt true in my eyes. even the suport has a monster of a shotgun that can tear through most pros. ive had situations where i took down a tank and two gunners with a shotgun and earning a triple. il be damned if those guys are taking the annihilator from me.
No. I agree that I would have a fun time playing a new game type, but it shouldn't be TDM. Something else would be much more appropiate.
