There's never any integrity with PvP, it's one of the many reasons that I usually don't touch it.
Even in a decent community like this, there's way too many people that just don't care. You think this is bad? The only reason it's not worse elsewhere is that other games actually have decent ways to filter out the bad actors. Here you get the full brunt of them.
But yeah I'm with you on the "delete ranked" at least. Or just take away all the rewards for it so that people who want it for itself can have it and everyone else doesn't feel pressured to play it.
