5 Chars Dungeon Powerleveling Multibox

[Apatheist]

this kind of AoE farming takes a lot of movement would take a very skilled boxer to pull stuff like this off.

You wouldn't need to play the same way as a boxer. Blizzard is actually relatively low DPS compared to arcane explosion. Cycling cone of cold to keep everything slowed while spamming arcane explosion is faster. I think the only reason those guys are using blizzard is because it's a guaranteed slow and it's difficult to coordinate every CoC/nova between different players. That's not a problem for boxers.

The problem with spellcleave comps is once you get to 55+ and start doing dungeons like Dire Maul and Scholomance. I'm not sure how effective it will be. The mobs hit a lot harder, have a lot more health and use a lot more special attacks like AE silences, etc. You'll be able to CC some packs but how would you handle bosses like Kromkrush or Rattlegore that can't be CC'd?

Personally I'd take warlocks over mages for dungeon grinding (without a tank.) Voidwalkers make great dungeon tanks for killing bosses you can't kite and gathering up multiple packs with your pets and then mashing hellfire is faster/easier than kiting. The only issue with 4 SL warlocks and a priest, as I've said before, is the lack of /focus so we have no way to assign pet targets.
