I am concerned about how the latest exploits affect jj2 game-play in certain levels. Wall-jumping in particular, because it can be used to scale up walls in ways that rf jumping can't, that probably breaks some levels. The good news is that wall-jumping is relatively difficult, much more-so than rf climbing.

Another thing, how does everyone feel about loose 40 sec shields in mp levels? - I don't mind the bubble shield in battle1, since it's easy to fend off with camping and careful playing, though it can be quite annoying in open-ended levels. Also, the shield in DW makes more sense considering the design and concept, although I'm not encouraging playing DW!
