yes!, I still think you should have a slow weapon, primarily because you WILL be spamming devastate.

Spamming devastate for treat o-O, men glad I dont DPS when you tank

I rarely use devastate tbh. If I tank one mob I do ss, revenge, 2xdevastate(4x heroic strike already with a 1.5 speed weapon and 2 devastates), this is for single mobs and bosses and you ofcourse replace a devastate wich is your weakest treatability with thunderclap every 30sec, demoshout ever 30sec, com shout every 2min.

So lets take a weapon of 1.5 speed shal we to get with the GCD.

Lets take a 2min rotation.

In 2min you'll do 90x heroic strike.
And if you keep on the rotation you'll do 2 devastates every 6sec, 20 rotations=40devastates

40-4xdemo-4xTC-1xCom=31 devastates.

On trash I might use it twice on a 3 mob pul and thats it...

A fuck why do I do this actualy, its a damn fact that faster weapon is better for both bos and multimob tanking by elitejerks ffs.

Be a noob if you want too but most tanks know better luckely.
