I ran against this comp last week....I've read more into it, there is teams with this comp at 2500 rating right now.
I play a druid healer with a ret paladin and a bm hunter ~1900 rated atm. Team we played against was disc priest/r sham/ uh dk. Lost to them 3 games. dk, sticks on hunters pet til I have to heal it(so I come out of stealth)...switches on me, stays on me the whole time until I die. I try my best to stay los, kite, root all the tricks I can. necrotic strikes + purges to my hots is hella strong against me. The only thing outside of tree regrowth spam I have rly is to get the regrowth jukes...even then I have windshear and mind freeze to juke. He'd usually save strangulate for tree form. My dps would always get one ALMOST dead and the priest would life swap. We didnt know what to do. Seems extremely viable right now...more so against me as a druid I suppose.
Anyone have ideas for this?
