Filled with determination
Grand hall is kindve a neutral stage the interactables there are kinda shit other than the engine thing that tracks really hard when thrown by a power character.That was my thinking as well. The TV's tend to be gone pretty quickly (either set with a bomb by spamstroke or thrown by me), but the respawning flower is pretty awesome.
Otherwise I was thinking grand hall with the teleporter.
Generally if youre a power character your best stage is arkham
if youre acrobatic or tech alley is really good
If youre a zoner go Ferris Airfield or watchtower (This is only if you have no dignity at all)
