Right now I'm wearing T10 helm and 4 T9.5 pieces and am using the reaping-less unholy build taken from elitist jerks. Dps is awesome, I mean really. In my guild I rate 1st on the meter unless there is a certain hunter in the raid, then I rate 2nd :P. On trash I get whispers from ppl asking how do I pull 10k on packs.
Now, I got the T10 shoulders and am wondering if I should break the 4 set t9.5 to get 2 piece t10 bonus.
At first glance, 10% more damage on scourge strike does't really look like it's worth having my blood plague dot not crit anymore, and trust me, on trash it really shows.
Is it worth it or should I just wait until I have 4 piece T10 to replace my T9.5 ? Note that the stat improvements are marginal from 9.5 to 10.
