I've seen many players single 4.0 PVP's skill balances and oversimplification as a concern, though there have been many who have praised the very same things. While I agree that there's not much flavour left after the simplification of abilities, the real problem that it boils down to is that there is NO ENDGAME FOR PVP

In my opinion, the changes that outright slaughters the future for this niche are:

The removal of all chat features in The Feast (4v4 and 8v8)
The inability to queue with more than 1 person in The Feast (8v8)
The inability to queue with anyone in The Feast (4v4)
