Ok, sorry that I have to ask this, particularly because I am using a barb... I might look very noob now, but I risk it:

1) How do you get 100% crit chance?

The tooltip says that you can have 1% increased crit chance (meaning on top what you already got) for every 5 fury.

My barb has 113 fury without having any maximum fury gear. The maximum fury you can have in addition is 35 fury having a belt, which gives 15 max fury, the IK set, which gives 5 additional max fury, and the ring Stone of Jordan with 15 max fury. So we will be at 148 maximum fury in total.

Now, casting HotA costs 20 fury. If you have the right ring, Stone of Jordan that is, it might be even only 16 fury because the ring reduces the casting cost by 4 fury. So we will be at 132 fury. Once HotA casted, we will have 26.4% additional crit chance. On top of what?

Let's check the top barb with highest crit chance in the world. According to DiabloProgress it is a barb with 63.50% crit chance: http://www.diabloprogress.com/rating.stat_crit_chance/class.barbarian

63.50%+26.4%=89.9%

So, we would be at 90% crit chance. Now, there are two passives that give 15% crit chance. And there is Battle Rage that gives 3% crit chance. So, if you are top crit chance barb you could cover up the 100%. Not easily, though.

2) How is this spammable?

Yes, there is no cooldown on the skill, but you have to gain those 16 fury back as soon as you spent it, otherwise your crit chance will decrease. Let's say we have Superstition for 3 fury, plus the IK set with 2 more fury. We need to produce 11 more fury with every hit. However, a hit gives like 6 fury (as far as I could see). We still miss 5 further fury. Do I miss something?

3) How this is unfair compared to other classes?

WD has 0 dog build, which isn't cheap or easy to obtain. Wiz can perma-freeze, which isn't easy after nerf, but still possible. Monk can (nearly) perma-stun. I saw even one reaching 100% dodging chance. DH can perma-gloom. And... [Insert here your own ideas of what could be op compared to other classes...]

I think, since it is not easy to obtain the 100% crit chance (or am i wrong?), and even more difficult to spam it, I think it should be fine the way it is. And yes, I am a barb, and no, I am not using this build (although it sounds interesting to try it out).

Edit: I just tested it and saw that a hit gives 3 fury only (not 6 as I said above). So there still need to be 3 more fury to be gained to make this build work...

Edit2: I don't know why my barb indicated 113 fury as base, but it is 100 only. So my whole calculation is actually influenced by this. Just wanted to point this out.
