In GW2 I need to dodge much more often. Aggro is bouncy and I often find to be chased by something that can 2-shot me. Auto-attack. Two skills used on intervals to increase damage (but only when I feel like I can go closer to melee range). Then there are three kits which I rotate frequently. At least try to swap to bomb kit every 20sec and drop the long cooldown bombs at feet of mobs, as long as it is safe to be in melee for a moment. That is swap to kit, use 3-skills, change. Then swap to granade kit and do same smoke granede, poison granede and frozing granede. Also use three toolbet skills (f2-f3-f4) on cooldown. Using healing skill pretty much on cooldown due to all the damage flying around. When I get hit harder, swap to med-kit. Then 1-2-3 on the run to eat some HP packs, leaded with 4 if I have some conditions on me, end with 5 for a buff and swap to another kit or back to weapon. All this while always watching the ground for often several red circles and running away from mobs chasing me, often more than one. And then look for downed people and try to ress them. I am sorry but for me that is much more frantic from what I usually did in WoW. And I for sure did more than LFR.
I am not saying that GW2 requires some awesome skills. It does not. Starcraft 2 or Street Fighter do. But saying that LFR > GW2 dungeons? Please.
