@ElementalFury106: Yeah, I think people often have a case of the 'wants it alls' and don't think quite as much about how the skills get used. If your taking non-stop damage skills that all fulfill the same role then... you can use that to burst damage by cycling their cooldowns but your going to run outa resources quickly. Sometimes that desire results in less effective builds as theres a lot of excess waste in like skills.
I find this is a bigger issue with warrior/rogue skills, mages are extremely diverse and you can at least make the excuse of 3 spells that all do similar damage as, hey, it's 3 elements you never know which one you'll need! Which yeah, makes sense though most things with high resist are only super resistant to 1, so... maybe you only really need 2 not 3.
Another thing is, more so with Warrior and Rogue - auto attacks pretty damn potent. Either way I'd rather spam Dragon-Rage then use some higher CD stamina draining skill. I guess I just look a lot at taking 1 skill, and using it, means a lack of not another skill or it's use, even if I have both bound. Whirlwind for instance, great skill really but using it is a sustained thing. While your whirlwinding your literally not doing ANYTHING ELSE. So it becomes a great skill to build around, but a shitty one to just 'throw into the mix'. or at least to me it is, im sure plenty of people are throwing it into the mix for the sake of whirlwinding.
Either way, I'd rather have 5 distinctive, unique use skills then 3 flavors of more dmg.

@LaughingWolf : Yup I asked mike earlier today and he answered with that exact thing. My 2H tank I have 7 points planned in Weapon and Shield specifically for the 4 passives. They're super tanky and fantastic so im pretty damn happy.
