Yeah, you are right. They are. I totally misremembered that. Skills don't scale in WvW, though, do they?. So level 10 versus level 80 still won't be completely fair.
I'm not sure about skills. I'd imagine they'd scale to their level 80 equivalent, but your gear still comes into play in WvW there so they'd be less effective than a true level 80 player.
What's up with having to pay for a bag slot and then pay for a bag? That seems pretty shitty. Is that how the first game was? I have been pretty interested in this game due to no subscription fees but that bag thing rubs me the wrong way.
Those are extra, beyond what you get in the game by default. According to the wiki screenshots it looks like you have 5 bag slots total counting the starting 20 slot bag you have.
