why is EWC on the old patch?

surely having ewc on the newest patch would be a good way for teams to show what theyre capable of on the new patch?
like instead of rewatching the same meta and seeing the same good teams do the same things and the same shitters do the same things, you could see what teams like VL, TS, EG etc could do on the new patch + good experience for stage 2?

bums cant even be bothered to organize a proper tournament yet wanna be taken seriously cause they threw money at it

idk ask aiminverylabs

I dont think riot allowed them as it would leak how players are gon adapt to next meta and riot saving it for london

I get this chunk of ewc not being on the next patch since it's not supposed to exist yet but if the main event is on the old patch that's wild
