Doors don't work very well in this game. I lost count how many times i wanted to get inside a keep (or out of a keep after respawning) and just couldn't use this one door. Sometimes you use it and find yourself back where you started, because it teleports you in and out, and in and out and in and out... On the other hand, some people can even use enemy doors.

Stairs are buggy too. Getting stuck under the stairs with the hammer is kind of a waste. Ending up there after using a charge/teleport ability, or getting sucked in by convergence, pushed in by a meteor etc. should not be part of this game. Then we have disappearing stairwells. Kind of annyoing when your enemy (or group) runs up invisible stairs that you can't use.

I like your ideas, but without fixing the numerous bugs first, i guess additions like that would just give some annoying players more ways to exploit and troll.
