I was wondering which armor set i should go with? stay with my 4 piece set, but instead of the tier helm im using the tier gloves, or should i just stay at the 2 set bonus and replace the gloves back with the original rep gloves? And also which is a good haste cap to aim for 25% or 20%, fully buffed of course? And also shouldi continue using the t11 shoulders or go back to the mantle of roaring flames?

If you're not going to use 4pc, at least use tier shoulders and legs, they are BiS hit/haste is too good to pass up.

Haste rating you should be shooting for is 2589 non goblin for that extra tick on Immolate.
