Greetings all and thanks for all the interesting reads!

I need some input in viable comps if possible. So far, I've been bouncing back and forth between 4 warriors/shaman and paladin/priest/3x mages. They are all around lvl 20 give or take a level. As been pointed out previously, the melee heavy comp is pretty dire to run at lower levels and I get bloody frustrated at times when 3 warriors are running off to pull two extra packs.

I have considered going the same route as some others in this forum, namely 4x caster dps and 1x healer. I'm leaning towards 4x locks/ 1x priest, but would like to have a mage at max level rather quickly . Would it be to much of a negative to substitute one of the warlocks for a mage instead --> 3 locks/mage/priest? I can see the utility upsides, but apart from that I'm not sure.

Any input would be greatly appreciated.
