Obviously it got a big buff. And i have no clue why. Nightblade has the best passives in the game (EASILY), the best class ults (EASILY) the best gap closer, the best cc, best instant cast dmg ability, and cloak. They were more than fine last patch. Now lets go over incap just to realize there is no comparison.
ult cost-50
This makes it one of the cheapest ults in the entire game. You can have this up pretty much constantly, especially with assault passive and pot passive, which is 40 ult immediately right there from a kill.
Damage
If you are running a high dmg nightblade this thing hits like a truck. The average nb has at LEAST 30k max stam and 4k weapon dmg. You can have 2k regen with that as well. With those stats its more than possible to hit 15k incaps, which hits harder than meteor even though meteor is 4 times the cost.
Other benefits
In addition to being up constantly and being one of the most if not he hardest hitting ult in the game, this thing now adds a guaranteed cc and applies major defile.
incap needs an increase in ult cost. Its ridiculous right now, although when playing a nb it feels sick and makes me want to defend it, ik at heart that this is over the top.
