Ugh, I have to say this post fills me with dread, as there was nothing I hated more in Guild Wars 2 than the jumping puzzles, I find them to be both un-fun and something to artificially make an area take longer to do (thus to make it seem like it has "more content" because you took longer to finish).
Ultimately if they say in small corners of the world and can generally be ignored, I don't mind a few being added for folks like the OP that enjoy them. I just hope they don't start to feature more heavily. Guild Wars 2 WoW is not, and I'd like for it to stay that way.
