Yes, I’m one of those players that ignores arena at this point because I see little purpose but it has not much to do with spec, it has to do with how Blizz borked the ratings system and made gear kind of pointless to go after given the short length of the season.
Arena points also reset, so it makes trying to finish the S1 set not seem like a very compelling activity, even though it’s superior to the blue set coming to reputation vendors next patch.
Like I said, you deciding not to pay for it and just logging off doesn’t really make a difference.
