With Kromtor's success in 5's I'd like to take a minute and talk about the viability of other 4x melee setups that could potentially work. With that in mind, here's what I've got:

Paladins: With Kromtor breaking 2200 in 5's *by himself*, the viability of 4x Paladins is not debatable. I guess the question is if another 4x melee is as competitive or even more competitive than the Paladins are.
Pros: Lots of burst, great survivability
Cons: No snare, No MS effect

DKs: Personally I'm less inclined towards the DKs than the Paladins. Shrug.
Pros: Great sustained damage, better than average survivability, 4x Deathgrip + 8x Chains of Ice available
Cons: Burst potential is lower than other classes, no MS effect

Warriors: I've been kicking the idea of these guys around quite a bit. You're gaining MS at the cost of survivability compared to the other melee classes.
Pros: Good burst, MS effect, snare, Bladestorm, Charge+Intercept
Cons: Probably lowest survivability, no healing available

Rogues: I could see these guys going both ways. One one hand, you're basically guaranteed to be able to insta-gib whatever player you open on. Are the survival cooldowns you have good enough to mitigate the fact that once they're gone you're just a leather-wearing melee class?
Pros: Great burst, MS effect, best snare, great defensive/offensive cooldowns
Cons: Bad survivability once cooldowns gone, no healing available

I'm not really considering 4x Ferals or 4x Enhance shaman. Other specs for them I think are more competitive. So what does everyone think? I'm seriously debating boosting up 4x Warriors... Just the thought of getting Charge/Intercept humped up and down the field while you're perma snared and MS'd sounds hard to deal with. Rogues seem really interesting to me too due to the MS+Snare+Burst potential.

I would love to get this discussion going and get some feedback!
