Archer c3 > Quarell c3 > ??
many people say that i must pick musketeer for rank 7 for the single target burst, but i dont see why its necessary, I already have a good single target damage cause of running shot + kneeling shot. So i dont think musket is really that good for this path, or am I mistaken ?
what other options do i have aside from musketeer ? Im not really into PvP
my stat build is 3:1 - Str : Dex
Thanks 
Falconer - turns your Multishot into a good AoE with Circling
Cannoneer - gives you actual AoE skills
Rogue - for Sneak Hit. This would let you leave your DEX and focus on STR. Also, you can copy land deployments with Capture, has a long cooldown though
Scout - Cloaking for mobility and Flare Shot as an AoE
-Cannoner may be your best bet, but don’t expect 1 rank of cannoneer can make your AoE as good as those AoE build cannon still has limited AoE atk ratio.
-Falconer maybe viable multishot15+circling is a really powerful AOE(but can easily be interrupted and long CD), hovering can protect you from few mob when you’re kneeling, hanging +running shot is another option when you need mobility while shooting.
1 circle for decent AoE is a bit hard for archer, maybe that why most people like to go ar2>qs3 so they have more free slot.
