It absolutely is. Hands down, +enmity is the best stat for tanking. Or are you gonna disagree with all of the testing that's been done proving this? Asside from the relic axe, no other axe has +enmity on it. Yes, you'll have lower DPS than with say garuda's axe, but only if your stats are at cap with garuda's axe. Most folks don't have capped stats.
Slightly Lower*
They're perfectly fine alternatives for people that also benefit from melds, so they're not the best, they're fine weapons in their own regard.
Giant Axe: DPS: 39.3
Scream: DPS: 40.77
Battle Axe: DPS: 39.77
They're not meant to the best weapon, they're merely alternatives and actually good ones at that since the way the stats work in this game, unless they're 3+ points over from each other (as in 39 dps - 42+ dps) it's very minimal returns in the long run till they optimize the stats more.
if you put 50 emnity on an ax then you get a 5% add to you enmity. I think you would get more then 5% enmity in damage alone using garuda over giants. Nerfed stats and nerfed WS is -emnity.
That's only true if your stats are capped, and as I said, most people don't have capped stats with Garuda's axe. It's much easier to cap you stats with the skirmish axe, making the additional enmity that much better. For a more realistic comparison as it applies to most players, parse damage with Garuda's axe with 10-20 STR below cap and compare that to the same gear but with the skirmish axe. You'll see that they are comparable.
I also disagree with the sentiment that the axe with enmity is the only useful skirmish weapon. The WHM staff with VIT added is also extremely useful in certain situations.
you can continue being wrong then.
The single largest benefit of Garuda's axe, as you yourself pointed out, is that you can add more STR before you hit the cap. But that doesn't do any good if you don't take advantage of it and actually add more STR. To do so requires at least triple melded STR gloves with +50 or more STR, which I assure you, most players do not have.
