Guild Wars 2

i did all the dungeons story and finished all with pugs
that wasn’t easy, but possible, you just need time and some type of organization
you will die often if you don’t prest attention and you can’t enter a dungeon as a full dps, everybody need something to support the team: for exaple thief got aoe stealth, and this can save from bad aggro…; necro got fear…; ranger got pushback and the pet…; mesmer got clone, jump, stealth…; engineer got towers, pushback…; war got stun, pushback…; elementalist got slow, knockback…; guardians…mmm…they don’t need anything, they are just op^^.
there is always something you can do, you just need practice.
about the loot, ye maybe they have to revisit it, cos getting always the same helm in all dungeons story is not really nice, but in explorable mode the loot is ok: you can get rare craft items, gold items, and tokens, so you can get whatever you want.
and if you really want the trinity back, i think that you just have to change game

Anet should implement a similar to gw1 build share
