These are quite good, but I have to question how fun they actually are in WvW. Firstly, why you’ll go for these after completing them, is mainly for the free siege blueprints. For some, money for siege blueprints isn’t a problem, but the more the better no? There’s some strategic value in keeping other teams from reaching them. So, that’s to say these are to be camped to a certain extent? I’d think the more serious servers/guilds will probably always have some there to discourage attempts or at least camp for awhile after getting their reward. Camping isn’t actually that fun, nor to the people who get caught and wasted time.
Secondly, these are jumping “puzzles” (and considerably long compared to the PvE ones). Puzzles are intended for people to solve. Well, first timers definitely don’t want to stay too long to try figure it out for themselves because that will get them killed. People will be more inclined to just find a video showing the solution and that kind of defeats their purpose doesn’t it?
The only fun here it seems is to encourage the sadistic tendencies in people to waste other people’s time. Now I have met some kind fellow players who didn’t attack, but that’s just not going to be the case for everyone.
