Just look at the numbers, really.

Fatal: 16 spell damage on 13 secs cd.
Phantom Strike: 13.5 damage on 25 cd (homing).
Double Slash: 9 damage on 9 cd.
Sweeping Cleave: 12 damage on 10 cd.
Power Smash: 13 damage on 20 cd.

To compare Phantom Strike to an average homing ability on a 20 cd, they have 7 damage or less. It has 13.5 (!!!) - highest damage in the tree.

You want to hear a crazier number?
With all of that, this is still one of the cheapest trees in the game.

QUICK EDIT: The truth is, the problem isn't related to the 10% ap from bladestyles. I wish it was, but it isn't. The tree should actually be looked at (unarmed as well, it's even worse in terms of numbers)

This is not the cheapest tree in the game. TO even get the good spells like power smash you need 60.
Compared to unarmed, which is 60 to get all the spells needed, you need 75. This is discounting sweeping Cleave which will push it to 85.

Armed is very expensive, and I would rather see the price reduced before anything else. 
Also, Fatal isn't 16 spell damage. It's 12

Melee suffers the most to slows because they no longer have the swift passive/active. So the only thing they can do is either get Garuda and pray for the best. If you want to defeat roots? You have to get Phantom Strike which was reduced in numbers. But, even then, you're rooted for the extra second. To defeat that, a Melee user would have to get Earth Attunement - Bone Reform which is 40 RPP spent or Water for Clenease or Mist Form. 25 or 35 wherever you go.

Melee, sucks. It's the skills that you need to get from other trees to make it decent. But even then, you don't benefit that much from them.

Fatal has bleed of 4 spell power. It is 16 spell power in damage (total!).
The tree, for dipping [which is what mostly happens these days with melee] is one of the cheapest trees, like I said. 20 for dash strike, 15 for fatal and 15 for pstrikes. Great. You can go deeper, you don't have to.

there is literally

no viable melee build without at least spending 70 rpps into the tree
