Make a good place to put a point to move down the tree
Improved Backstab (2/5) - If you use Backstab, this talent is essential. This increases your chance of a critical strike by 30% Last Chaos Gold, so you are looking at 50-60% chance of a critical hit.
In groups where you use Backstab, this translates into a ton of damage. If you do not use Backstab, this talent is obviously useless. And really, if you are in this tree and have daggers, you’ll be getting Mutilate. My pal and I are playing dual rogues so we wanted a good build, but could not find one that actually worked good enough. So we decided to make our own...this is what we came up with:
Relentless Strikes (3/5) - 25 Energy if you use a 5pt finisher, it is not a whole lot of Energy back but it is practically the cost of an eviscerate. Since the cost is 1 talent point, it makes a good place to put a point to move down the tree. This does make a 5pt Slice and Dice free.
Improved Expose Armor (1/5) - Expose armor loses nearly all use past level 30. The max it will do with this talent is 3075 at level 70. Now put that into perspective, paladins and warriors will have around 8000-10000 armor. NPCs will have even more.
Compared to Kidney Shot where you completely eliminate all chances of you getting hit for 6 seconds it offsets the increased damage you had get from this talent. Considering it is a skill you will not ever use in a group that has a warrior, it is not worth it.
