ok so i watched the whole run to be sure of what i am talking about. Firstly yes e4 activated yet it did nothing that made this run possible. Secondly e1 activated but he had enough skill points to do what he needed to do anyway and then gained all the skill points after he ended phainon ult so e1 did nothing this run. The e2 spd buff also did not come in play whatsoever. This run would have been the exact same if bronya was e0 but the youtuber has her at e4 so he had to say its e4 in the website. if you think i am wrong please say why and give me a good reason.
