Hi - I haven't been playing WoW or multiboxing for a long time. In fact, the last time I multiboxed was during WOTLK I think

I've levelled up my DK to 110 and I'm thinking of delving into multiboxing again. I like challenging myself with dungeons - previously it was heroics in WOTLK and the associated achievements (until you could just bruteforce most of it). I used to play a team of DK (tank), Mage, Shaman, Druid, Priest (healer).

Anyway, I'm looking for a good composition to spend my level-up tokens on. I see most buffs have been removed and I was thinking of just going DK + 4 SHM (3 DPS + healer). Perhaps swap a shaman for a mage (poly), but I'm not sure if the added utility will be worth the simplicity traded

Considering I'd like to see how far I can get in Mythic+, I'd be very appreciative of advice with group composition
