I just listened to the interview on Doc Holiday and I wanted to make a point that was just brushed over with no real response to (about 38 minutes in). Skills reset on raid boss fights! Shouldn't this significantly affect the worthiness of this set bonus?
I feel like Graal may have missed the main point when responding to this question. He said the skill is awesome, and that's not outweighed by the penalties. I agree with that. He also said that the skill keeps you from dying, which is awesome and thus if you can do that more often it's more awesome. I also agree with that in theory but I don't feel like it applies when our skills are guaranteed to be available to us at the start of every raid boss fight. The problem here is not what skill is affected by the set bonus, it's how it affects that skill. Extending the duration of the "Invincible" buff, reducing the penalties somehow, or reducing the duration of the penalties would all be great ways to enhance this skill without rendering the enhancement close to useless against the average raid boss (which is what I would assume the set bonus should help us most against anyways). If Turbine continues creating raid bosses similar to what they've done so far, it will be a rare fight that both lasts longer than 10m and has significant chances of tank death from start to finish.
I also assume this set bonus is meant to help us be better in raids, being a raid set and all. This is why I'm focusing on raid fights and its utility in those situations.
P.S. If Graal ends up reading this, big thanks for that interview. I really enjoyed the insight from some of the team, and I'm very happy with what I've been hearing about Isen. I only felt like there was a real opportunity to address the main issue most of us have with this set bonus, and while you made excellent points on the utility of the skill, that isn't our concern (at least not this one )
