Battlegrounds are only good if you have 650CP allocated to specific stars and specific skills picked with specific morphs with specific gear and specific weapons. If you do not have the exact prescribed PVP build you will just die constantly and be no use to your team, which I guess could be considered fun for some but not me. I tried and it was not fun. My characters with PVE builds died within seconds and were not able to fight back.
I wont be queuing up battleground either because none of my characters are built for pvp and the game does not have a simple method to quickly swap between builds. For example my sorcerer has clanfear morphed which is useless in pvp but I not running to a shrine and redoing all of my morphs just to switch one spell for battlegrounds.
CP are disabled in battlegrounds, you can have either max or just 10, it would be the same. Besides, the max is 630, not 650.
So I just played my first Battleground. Was matched against a Premade and we were completely stomped. On top of that I was hit with a deserter penalty. Premades are no fun to play against, but come on ZOS I stuck with the slaughterfest. I didn't deserve a Leaver Penalty. I guess No dungeon runs and no BG's. As much as I hate cyrrodil I guess I'll go back there -_-
