This isn't really a Bulba issue in regards to Mirana. She has been picked 41 times this TI with a 53% winrate. 132 combined picks/bans, and the 4th most contested hero of the tournament behind Alch, Ench, and SD. You can argue they were bad Mirana games (I don't think they were) but it's not like there's no rhyme or reason to prioritizing her.
How many of those games were mid mirana?
Both teams (OG and EG) looked unstoppable with enchantress on their team, that's all there really was to this match, imo. People keep talking about being unable to ban OG out of a match, but EG was the same way today. EG got ench game 1 becacuse OG banned lesh and naga. OG got Ench because EG banned wisp and magnus.
Either you ban the enchantress or you give one of these top teams something they're really good with. Ench was what allowed EG to punish mid and take game 1. Ench died 5 times in game 2, but it didn't matter cause she slowed down TB early. game 3 EG directed their draft around killing ench and you saw the result.
PSG.LGD first banned the ench against Vici, i expect them to do the same against OG. I actually have this feeling LGD will give them wisp
