Rumble Ult buggy
TL,DR: AOE does not match visual. Damage too large per interval no time to react.
so I was playing as shen and we fought then rumble ulted. I had w up so I was safe. in fact I was outside his ult walking up to it fully aware of it making sure to stay right on the outside I built full HP this was mid game so he wasn't fed. had decent Mr from runes too/mastery. had about 17% HP left. and I somehow instantly died. I could have w if I noticed my health bar ticking down as one would expect DMG over time to be like.
anyways I'm here to report that Rumble's ult aoe does not match the visuals. you can be right on the outter edge of it and it still hit you. I also think it needs more ticks and less damage each more like malz drain where you can clearly see your HP gradually go down. letting you know exactly how long you have.
there was a varus too on our team. as soon as we both died to rumble ult after fight broke loose (rumble had ulted right as he died). we both typed at the same time how the visual didn't match the AOE DMG.
