Level Syncing isn't the best solution

[Rhomagus]

A level high level tool kit is more complete then a low level. That makes balancing nearly impossible, nerfing numbers does not change that fact. A high level is better equipped. That is the issue with this idea. The solutions are strip high levels of abilities or grant low levels a full tool kit..

Just nerf abilities above the level of the dungeon. Players who've unlocked them can either choose to use them or not.
