Capping 1260 without DBW isn`t even remotedly a hassle
It's not a hassle but you lose lots of stats/gems, you're gemming 7gems just to replace just DBW, assuming you're using apoc hc you will have only 4.62%hit rating so you're forced to use the t10hands or polar. so gemming is very tight compared to a DBW user where the haste is by no means as bad as you make of it, haste is not a bad stat for bdk. with a value of 2.13 it's pretty darn alright
Gemming with a dk is pretty tight, we do not have the luxury of being a warrior/rogue having a bowslot where they can easily reach hit exp and arp cap without sacrificing one of them to be lesser. Which forces us to gem to reach them.
