How to Fix Sentry
1. Each Reality Warp charge increases the chance for a state to trigger by 14%. This means consistent 100% state procs once at 5 charges - rewards build up time!
2. L1 fury chance changed to 100%. It's a 20% non stacking fury, no reason for it to fail.
3. L2 armor break chance changed to 100%. It's a low armor reduction no reason to make it fail.
4. Regen increased to 15% of base health. Too low currently to warrant saving up to an L3 and expending a reality Warp charge.
5. Optional - Add poison or incinerate immunity. This guy has the power of a million suns, I think his body can resist something!
There you go, Sentry would be a viable and rewarding hero.
