Since you've played the game before (didn't say what level but I assume you got to a decent one) - No I don't think it would be worth it for you to play this now and you should wait for the open beta when there won't be any character wipes. The game is fun but all your progress will be gone sometime soon-ish.
Nobody is sure when the open beta will be, but it definitely won't be until next year I'm sure. It will how ever long it takes Daneos to fix all the bugs and get it up to a good state with 90+% of the content in the game. Could be another few months or more, not sure.
