Fractals, crashing, groups, progression...
ArenaNet needs a dungeon saving ability. Also, the lack of waypoint in the fractals makes dying dumb, in that in some fractals no way for group to rez you because of positioning so you have to wait for the whole group to die (plain stupid mechanic). Also, some rezzing bugs in which you can’t continually rez someone has happened too (you have to keep hitting ‘F’). Fractals need waypoints in them period.
Some form of waypointing system would be nice in them, if it makes bumrushing tactics useless IMO.
A working lfg system would be best, something that isnt based around which server or overflow you are on. The lfg system has already been successful in older games so I dont see whats so hard for Anet to do about it. If they want to start going down WoWs road with tier progression they might aswell implement the only fantastic aspect of WoW dungeoneering i.e RDF (LFG tool).
