5.0 Warriors happened.
and yes, i get the irony
This has nothing to do with anything,
Every season is the same, something super dumb happens.
There has never been a season where there wasn't something extremely retarded. From S1 to now.
I'd say a huge reason why PvP is dying has to do with boosting and title selling, most legitimate players (who aren't capable of getting Glad easily) are quitting because they don't see any point in playing when they can't get higher because of people buying titles.
Those players aren't being replaced by new ones.
