Well we got nerfed a bit from beta to release but I still love my Dread. Ever since UO I've been in love with the Tank-Mage and currently DKs are the closest too that.
Debuffs, DoTs, LifeTaps, Fear, & a nuke or 2 to go with Tanking, what more could you ask for??
I think the class gets especially fun at Lev 10 when you get Shadow Step. Seriously one of the sweetest abilities in-game.
My one and only complaint is true for all melee classes and that's how endurance regen is done. I just HATE it. 20 END per tick but a tick only goes off after 2 seconds of you not doing any other ability that uses END. So you end up having to wait a lot, which is very annoying. I'd much rather they would make the ticks every 2 seconds period, none of this stop using abilities crap.
Dreads with their spellcasting aren't as effected by this but it is still annoying IMO.
