Devestate or not to devestate?
This is just to discuss the pros and cons of aoe tanking w or without the use of devestate. As stated in previous posts I'm against the idea of using devestate to aoe tank- here are some arguments to support that fact.
The idea of tanking is to do the most dmg while keeping all mobs under control and/or aggroed. Devestate fails in a couple ways of accomplishing this on multiple mobs. One, it's dmg fails- devestate does horrible dmg unless your target has 5 sunders, and even then shockwave, cb, ss, even revenge, will typically do more dmg. But threat is the point you say? Yes, keeping aggro is top priority- otherwise we'd be dpsing. With cleave and the clap you don't need sunders on targets, muchless with shockwave, ss, cb, and revenge to throw around at low threat mobs. All high dmg, high threat- efficient! options.
However the opposite is also true of bosses. Nothing is more efficent at gaining threat and stacking sunders than devestate/swordnboard ss combinations.
Devestate is also very useful for keeping spike threat in check. A Mage blows cooldowns and pounds the sheet out of something, often a taunt followed by two quick devestates will remedy the situation before someone gets hurt.
But once again imo using devestate for aoe tanking is overkill and inefficent. Its like a warlock dotting up trash mobs, they'll be dead before the full dmg is done. So why devestate and do horrible dmg when you can spam cleave, clap and all your physical attacks? Because it's easier? The tanks second priority should be pounding out as much dmg as possible. On single targets devestate is fantastic, but I strongly believe that in an aoe tanking position it is highly inefficent.
