It doesn't make me mad, per say, but it's not something I like. Ultimately they are a business with costs that need to be paid for somehow, and if you're not cranking out new $60 titles to millions every few years it becomes difficult to pay your employees and keep the servers going for your customers. I will say I think there are a lot of great things to spend gems on in this game, and I don't mind account wide storage upgrades like the bank slots, but per character bag slot extensions is something I dislike. I picked my warrior as my main character when the game came out and upgraded her bag slots, but every other character suffers with the default bags. And I've spent a good amount of money on gems, so not like I'm stingy or anything; like I said there are a lot of compelling items in the gem store that I do buy. I think Anet would be better served making them account wide so customers feel like they are getting better value for their money and thus more likely to spend it, but I'm not their economist.
