Dead Eye Barrage build

Hi,

I finnaly find a way to play barrage build to Tier 16.

There are a lot of arrows who chain and fork, that pretty cool, but i don't have enought damage at all !
and i don't know what change now.
Even i had 50 exalt to put un this stuff, how can i go to 27 000 dps with all my buffs in game on barrage skill to at least 100 000 ? and when i see some buids on youtube, 100 000 is really really low.

Do you have a suggestion please ?

THX
