A full DoT ailment build using a bow certainly seems to be possible, i started leveling a new character for exactly that. My plan is to apply the 4 DoTs with autoturret, wailing arrows, phantom blades + evasion, and gunslinger's brand as my main spender. Combine them with stasis aether gems for the which time cannot heal node, and also the dire juncture + fatal pact + frenzied blows + rage per hit taken nodes combo (which i just read about earlier), and i'm hoping that i might finally have made a strong build of my own that isn't a copy + paste from some streamer or youtuber or whatever.
Either that, or i'll try using the infi-rage combo with the augmented ammunition modifier for gunslinger's brand and find out if that one skill is enough, without all of those other bow ones.
I don't understand why people google and copy builds tbh, experimenting and discovering fun ones is where half of the enjoyment is i.m.o.
