I think the MMO community needs to stop trying to put up these virtual walls, because it's not helping build the community at all. Those that are struggling for map completion in WvW, should just learn to accept and appreciate that it's harder for them to achieve than others might. A lot players seem to be under the impression that even something that "appears" to be basic as map completion should be easily attainable. Even if it is, not everyone is going be able to do it. I just think players need to be more patient and keep trying, eventually they will get that chance to complete WvW maps. It's just going take longer, and there's no harm in that. There's no rule that says map completion has to be achieved in limited amount of time, especially considering GW2 is a non-subscription based game.
It's not helping anything. It's not helping to get them into WvW or PvP in general, and may in fact turn them off. It's not helping the people who want to genuinely play WvWvW. It's certainly not helping ArenaNet's "play how you want to play" mantra. The only people it helps is the people who get their jollies out of ganking people who didn't want to be there in the first place.
I'm all for WvWvW being a mixed PvEvP environment - but it has to be one that people go into because they want to, not because there's some achievement that is 90% pure PvE that they're forced to go into WvWvW to complete. I would also, incidentally, say that the PvE portion needs to be more tightly interwoven into the PvP, so that if, say, a group decides to attack a centaur camp or, to be more cunning about it, lure a powerful monster to attack another world's stronghold, that can have ramifications for their world's overall tactical position.
