Started to do arena as resto druid with my bro (mm hunter). What stats should I aim for to be able to get ~1800+ in 2v2? (resi, hp, mana, mp5, +heal etc)
Well looking at your stats, the biggest thing would be your +healing. If possible try to bump that up a bit to around (or higher if you can) 1700. Your other stats seem fine, but obviously going higher than recommended is a good idea too, just don't sacrifice any +heal or other major stats to do it.
