I feel as though it needs saying
I believe that the fact that Master Yi can do the amount of damage that he does while being immune to burst (his weakness in team fights) is slightly ridiculous. I also feel like the driving force behind this build is Sterak's gage. I think the mistake with designing sterak's gage was tying it to taking damage, something that literally anyone can do, not just tanks and juggernauts. I think there should be a soft gate, like Warmogs that says you have to have atleast this much health (Which will increase over time as the game goes on) to use it's passive ability, putting it just out of reach of champions that abuse it (ADCs, every DPSing devourer jungler who wasn't meant to use it)
