There were definetly less ppl in BGs when CP weren t allowed. Moreover the matchs have been usually more interesting with CP since many great players who weren t playing without CP came after the CP were added.
I hear a lot about the imbalance of CP etc... but I do believe that CP actually allow the less skilled players to be a bit more competitive ( even when they have only 450-500 CP ). In no CP bad players just die in 2 hits by the "good players " who are usually the ones at CP cap anyway. I am pretty sad ZOS ll turn BGs to no CP again because a minority ( I believe it is a minority since BGs are more crowded now, but I can be wrong ) is complaining on the forum.
That s only my opinion and I ll keep playing BGs after next update since I love them and since I usually play in no CP campaign. Time to sharp my stamblade
