Hots and Dots

I have put together a new team recently which I am finding to be excellent so far (currently around level 62); I have already promoted it to my B team despite being the 4th team I have started :). The general premise is to use as many "over time" effects for both healing and damage as possible and hence have the most mobile PVE team possible. I am currently running:

Druid Tank - I don't have experience with druid tanks but he can aoe on the move easier than the plate tanks and the big hp pool fits the healing method nicely.
Shadow Priest - Nice dots and good buff/debuff synergy with locks
Affliction Lock - See above
Affliction Lock - See above
Druid Healer - Only real choice for totally hot based healing

DPS seems high and downtime is non existent (thanks to an innervate shadow priest macro)

I have never played any of these specs at high level, but it seems awesome so far and after what I have read about cataclysm, the movement it allows may have distinct advantages. Has anyone else tried anything like this, and if so how did it turn out?

Come Cataclysm your whole strategy will be torn apart unfortunately. Tho for now its fine :) too many class changes are coming and such to make a team like this work the way you want it to.

If you were truly after all hots/dots why not take a dk tank? They give great buff to the dmg of the group and have dots as well :)

I could bet that team will be just fine in cataclysm but what comes to tanking i woudn't take DK even if it gives more dps, i really would take feral or even warrior tank... Those tanks just have much beter movement + tanking rotations for my taste

I tried to use my DK tank with my new ret paladin team (they dinged 60 last night) and found that the paladin just felt better. It could have been that I was more comfortable with him, but I think it depends on playstyle. The Blood DK tank has a lot of "oh crap" buttons, but there is someting about paladins and their usefullness to the rest of the party (hand of protection, lay on hands type stuff).

I used my druid tank for my mixed caster team and he did fine with swipe for AOE but I still missed the lack of panic buttons for the rest of the team. You have feral charge, bash and growl and a 10 minute aoe taunt, but not much else to help out, it just seems like the paladins have more (i'm probably biased).

I don't rely on my tank's dps too much (except while boosting). I say pick the one you are most comfortable with.

The druid does seem like the best to go with the mobile theme, nothing beats swipe really...
