Unchained...nothing stays the same (but how do YOU use it?)

[Merkava]

I'm confused here. Is it better because it does some extra enmity ?

In that case it just isn't necessary at all. The extra enmity doesn't matter one bit if you go the SE > BB opener like you should.

And the extra range of tomahawk ensures a better positioning and a smoother CD usage in my own (humble) experience over the past 2 years and half

Pretty much this, I can understand where people are coming from when they say Overpower is better but WAR doesn't need the extra emnity at all. Tomahawk offers better positioning and slightly better CD usage and if we go into details we can even mention that Tomahawk does have more potency and cost 10 TP less.... but not that it's relevant at all.

I could see where having slightly more enmity for picking up an add would come in handy (bastard t13 adds come to mind, tho prepped SS or BB is better for aggro), along with the faster animation they updated a while ago, it probably pulls faster than a tomahawk would in that case, tho I'm just guessing based on memory atm.

There will always be situation when pulling with Overpower is better, nothing is ever set in stone. It just seems a bit... needless against a single target (boss).
