Bishop's Champion Design is horrible
The thing about bishop is that he is meant to be a hard hitting champion with his special attacks. The main issue is that you may get punished for being too greedy. The degen you recieve when you have 40+ prowess charges is absolutely horrendous and needs to be toned down. His regen cant even keep up with all the degen he can recieve. This doesn't even require a champion balance or rework of any kind... just reduce the damage he takes from it! Champions shouldn't be able to kill themselves especially that quickly.
