Ballista Build - Commander Bow?

Hi everyone,

I was thinking about trying out a Ballista Deadeye build. Read some guides and stuff and often see the Iron Commander as used bow for these builds - even with Artillery Ballista.

As far as I see it a rare high physical bow should be far more efficient???
So why the hell everybody seems to use the Commander bow? 30-70 physical damage seems extremly to low for endgame???

Even with 1000 dex the bow goes to 70-190 which is fairly low?
Can anybody explaim me why?

Thats because the secret of the Iron Commander does not rely on the physical damage it increases with (ofcourse it counts) but the amount of ballista you can procude. Example you got 2k dexterity, an single ballista does 100k dps,by default you can have 3 ballista PLUS 2000/200 = 10, 13 Ballista. 13 Ballista x 100k Dps, solid 1.3m dps
