I started a DK last night to get some practical experience before deciding one way or the other

So far, seems like playing a warlock, the pet feels like my felguard, I have dots and double deathcoil ^^, only downside is I have to be in melee range to apply dots - but now I have a bigass axe, and plate =D

Thinking about it, I can do all my outland leveling with the druid healing me but not grouped - benefit of being less gankable, and minimal downtim, and no exp penalty - looking to min-max talents to be efficient from a damage output perspective, rather than efficiency of damage / regen. Still researching that, gone unholy for now.

What is the state of 5mans with reguard to healing complexity? Unless its unmanagable with a DK mainscreen, I think this might be my favourite duo of the options.
