Not op at all and not even a problem. For the record i have one of each and run void on the warlock.😉 I have killed many many self rez sunbro. In fact in the fly in for trials or elimination if on pre fight inspection i see them running self rez i am happy because they are so easy to kill. If they are running radiant skin i have more concerns. Any decent sniper or shotgun will kill a rez before they have time to get out of animation. As there only ever 3 on other team its not that hard to see who running what and remember the names to watch for rez. If fact its part of the game strategy to know when the team should be getting supers through just time or earlier if they have got a few kills so as to be ready for it. I have also bladedanced titan smashed and nova bombed them on rez too. I often active bladedancer and watch the ord of sunsiger on final round ready to razor and slash. Same with others 😉
