Crests for finishing a run needs to go to 15
There needs to be a catch up system for crests for alts and new players.
Dungeon timers are to tight for some dungeons with out doing big pulls that a lot of the time in higher keys will require a CC rotation which in its self favours bringing classes with good AoE CC shifting the class verity in higher key. This in itself is not the worst thing as its an interesting gameplay experience but for pugging keys and newer players without external addons or weak auras its very hard to find enjoyable.
