Why bother making modifiers at all if 90% of them can only be used in the 5 basic scenarios? That's only 5 levels. Play through 1 a few times with a couple different mods and then we're bored with it.

This is probably the most requested thing in suggestions yet we are ignored. There is no good reason I shouldn't be allowed to throw fireballs around dragons reach, or fill the rock concert with zombies, or have a gun fight in halloween town. Come on devs.

SOME levels could be broken by use of the chaos ability or by randomly allying with the boss but levels are frequently broken simply by too much fire in the level causing things not to load in or an enemy getting launched into the ceiling by a random hat dropped by a pimp or cowboy. The solution to something breaking a level is reloading and always has been.
