dual boxing a feral one resto is basically unkillable, the healing hot keys arent hard since you can really do the healing all on 1 button with a good /castsequence macro and buffs on a second key and just use assist for targeting the buffs you dont need to actually use the tree then.

managing to ferals in combat is an arse pain but doable i did it for 40 levels on my two taurens i then switch 1 to resto and i still use her to in cat a lot the easy way round it is to run through the mob with your main and then turn it (which is an old tank tactic anyway) your second toon will automatically be behind it then, and yea does need a lil management on both screen but feral/resto really are fun to duo box but thats pve.level experience pvp they would suck balls due to it being way more intense and unpredicatble.

nother good combo warrior/resto druid spec fury and basically you can rip through anything in seconds. pull 3-5 mobs with your warrior well you druid sits safely at a range critting regrowths is insane i hit 54 this way in just over 1day 4 hours on a raf account and my warrior was in level 30-36 greens and out killing most people i met.

anyways thats my personal experience what i like may well be totally "Carp" for anyone else.

just one comment fury warrior resto druid, warrior has 100 rage non-stop cause you dont stop to rest and druid never ooms because well its a tree and they never oom. so you can pretty much kill nonstop permantely from log on to log off.
