Its not so much the crashes, its the frequency of them. How many times is this today alone? 5? I expect it to be rough at the beginning, but this has been an issue since the server has had a load on it and its not like the dev's didn't know about it beforehand. I hope they can get it together and get this game stable, I do enjoy it, I would just like to play it.
In all likelihood it will crash more frequently when the game opens up to everyone Feb. 2nd. It's hard to predict what issues will pop up as server load increases. All you can do is deal with it as it happens. I guarantee you there is a team at Cryptic scrambling to get this taken care of right now. I believe they will get this game stable, it just won't happen overnight.
