I've had builds that lean on Unstop as well.
Again, there are other, cheaper, better ways to make yourself more durable WITHOUT a suicide button.
Because the crash and the MANDATORY RESET due to bottoming out your blue bar and tanking your Recovery is just that.
You, the guy dragging most of a team's aggro has to somehow withdraw from in your face combat, hope you don't get chased down, and then reset all your armors.
Build plan?
