While I really want to play this game, I decided I would rather just hold out. The server issues remind me of the issues Blizzard had on release, which is a good thing since it means huge interest, but will become a bad thing if they don't do the rapid server deployment that Blizzard did leading into the first few days of the WoW launch. I don't want to pay to sit in queues most of the time.
In the end, I want to see how it evens out. If in 6 months the game is still as popular as ever I will sign up, since I can afford at least one more subscription game. I notice a lot of MMOs these days usually release with a subscription and then within a few months revert to a F2P model, so I also want to see if that ends up happening here or not.
Either way, have fun and see you guys in the future!
