Yes, agreed PVP is broken. Not sure what their algorithm is based on but it doesn't work. I just leave it on auto now as there it's not fun or a challenge especially when the opponents have the best spells that I can't even get.
I couldn't agree with you more. PVP is broken. Either the opponents are too easy or unbeatable. I just put it on auto because it really is not fun. Additionally, everyone who has been around for a while has the best spells and there is no way for newer players to get them.
