I watch Bisu a lot, and to me, it feels like he doesn't have confidence in ground army playstyle vs terran and will switch to carriers sooner or later. Can't blame him, it's also pretty much a trend now as well.
Direct causes for his losses? Polypoid --> vulture raids, that was enough to set the game. Invader --> micro with reavers not good enough / not enough value. His engagement was also bad, maybe he got his obs sniped, i don't know; it's always easy to judge with maphack ; Slow zealots is pretty normal at this stage of the game.
His mistakes weren't that numerous. It's sad for me that u judge the players, and not the games.
as a low level player, his engage on Invader made no sense because a) he can see Terran does not have a 3rd base yet with 6 fact, b) he only had 6 gateways and 2 carriers making so does not have army advantage. Seems like he should just buy time as long as possible until carriers and interceptors.
since you know more about the game, do you disagree and think it was a good decision to engage and just bad execution?
well, i mentioned in my previous message that the engagement was bad, there is no sugarcoating it. But he needed to engage somewhere, at least partially, engage, do damage with reavers, trade zealots, then disengage. Meanwhile Bisu seemed lost with his 2 shuttles, that were both killed all too easily and engaged when terran was in ok position to receive him.
Until the moment of engagement his reavers werent used enough either. Such a build really need some good work in micro, with reavers, or favorable engagements and Bisu certainly failed to show that.
