Tried challenge modes first time today, great fun. Got gold on two of the easier ones.
There was no haste buff.
My question is whether resto druids in CMs without the haste buff should try get the 5316 unbuffed rejuvenation breakpoint, try to minimize haste, and if so, to what extent? Would it pay off to ditch red-slotted haste gear for gear without red slots?
Haste is the cheapest uselful secondary stat, at 420 per %, compared to 480 for mastery and 600 for crit. The extra rejuv tick is great but haste also makes efflo tick faster, and shortens the cast time and GCD of regrowth which increases throughput - with less mana efficiency than mastery. Around 20% of my healing on the runs today came from rejuvenation.
With my current gear I can reach the 5316 breakpoint by giving up 80 intellect from gemming. In practice it will all be taken from mastery. Would that be worth it?
