Power vs Condition...
Conditions no question about it, more precisely you want axe+torch, drake and any form of condi build you feel like you’ll be able to aoe common mobs very quickly and the weakness axe gives makes a drake able to tank just about any champion in open world too, if you like shortbow you can keep it but use as secondary weapon for single target.
Axe/dagger works too, but axe is a MUST for conditions.
Shortbow’s skill 2 is AoE too, by the way, so it’s useful for poisoning targets – especially if running the Torch version which has no other poison source.
Condi builds for PvE roaming are different from power builds, mind. You don’t kill things, loot, move on, kill more things, loot etc like power users do, that would be slow as hell.
You condition them to a certain number of stacks and usually <30, <40% hp, then start moving on, harvesting a resource node, etc. They’ll die in a second or two, then AoE loot while running. Also, never fight 1v1, it’s slow. Kite 4-5 mobs then kill them all in the same few AoEs for double or faster kill speed.
Power works, but stay away from LB and use the Sword. You’ll be weaker than power builds from other classes though, but it’s good enough for open world.
