So there was a thread made about the error in the skills description already [I can't seem to find it atm] but basically someone pointed out the new skill is missing the anti stun as described. Surtr responded and said this was intentional by the devs [meaning they accidentally added that description from the old last stand and the new one WASNT supposed to have anti stun]
Positives of this "upgrade":
-The skill works as a buff and lasts 3 minutes, it will tick even when stunned and you don't have to click [besides to rebuff after 3 mins have passed or if it was ticked which has a cd]
-The skill also in a way works as a deaden nerve as I've taken more damage than my hp was before and the skill merely reset my hp to 50% or something after the hit.
There is only one negative but it's huge. As seekers we are very prone to cc. Even with the new voidstep anti stun these classes like dusk and sin easily can wait around for the 20-30 seconds of all our anti stuns and then pwn us. With the anti stun after tick that would be life saving, w/o as long as they have you stunned or held in place it really just makes you a bit tougher.
We should demand the skill to have all the features of the original or in some ways it's a downgrade to an already not OP class.
