Is really good for Sen is it not. Like they will most likely loose to G2, but because they have seen so much maps from both MIBR and Kru they have a huge advantage.
Sen also have the advantage of not having shown many maps and seeing MIBR weak lotus and Kru's weak Attack side Haven, while also seeing Kru's strong bind.
So I think if Sen loose and go into the lower bracket, the map they choose will be Lotus. And since MIBR perma bans Fracture first and Kru perma ban fracture or pearl first, they will have to give Sen lotus.
