Why can't we get tier points anymore?

I get that the season is over but tier have nothing to do with ranked, you’re telling me I spent 2 to 3 months doing PvP weekly, facing the worst, toxic part of the community, just to be 1 week short of reaching extreme, despite it having not a single fucking impact on the PvP season or ranking, all it does is giving access to the shop???

Fuck this game and fuck its PvP
