My Patience and Time is fully upgraded (not the attack, just all the performance changing skills). The stealth ability is honestly nothing spectacular. If your scope glint didn't still show and the stealth activated immediate upon zooming in instead of after 3 seconds (lasts 10 seconds) then it would be amazing. I guess it would also be OP then too. I hope Ice Breaker performs better honestly, although it sucks that literally everyone will have one now.
