Payload arena? Where do I sign up?!
The new "raid mode" really seems like some sort of tower defense game ala Monday Night Combat, Dota, Dungeon Defenders etc. Honestly I would be a bit disappointed if true since there are already a multitude of games with that mechanic, so I hope they have a really interesting twist to it.
One mode I'd like to see in TF2 is something similar to conquest in Battlefield, where there are multiple cap points, but they do not go in a straight line, you can cap any one at any time and after you either capture all points or hold points for a certain amount of time, you win.
