Please understand that although the team is called "Balance" for the purpose of player interpretation, their role is really just to make the game a bit different every now and then. They've said as much on the WvW livestream many, many times. Think of them as "Meta Mixers", rather than developers who strive to "Balance" the classes - whatever that nebulous term might mean to you. This would be true if holosmith recieved nerfs, but it doesn't get any so it remains the top class and none of the nerfs to other classes are enough to change anything.I can't speak to recent PvP/WvW metas, but I know that it doesn't really seem like a 'meta mixer' when, like you said, nothing changes significantly. It's hassle for everyone for almost no reason. Some changes were great (shatter, shades), most were miniscule.
