The only assumptions I have of ANet is that GW 2 will come out during the year of the Dragon, 2012, and there will be a special flavor of event(s) leading up to that date. Unlimited Dragon Arena has been just a fantasy of mine and some other heavy PvP players over the years. There have been occurrences in the past where the admins were a tad slow on turning off/kicking all us out the servers a few times. Oh and Dragon Arena is horrible for points towards the
Gamer title, which also ironically happens to NOT count as a
PvP title 
Dwanya vs Grenth is the better rewarding format. We don't even need to jest that there won't be a mass exodus to GW 2 on a count of how many people are still joining GW Classic even now. It's a non-issue since I personally would definitely continue to jump back to GW Classic for DA events. Granted... there isn't some even more awesome event in GW 2 at the same time!
@all
Jumping into the current permanent PvP formats is a player choice and if they get abused by botters that's just something too unavoidable at this time. Dragon Arena has always seen plenty of geeked out PvP freaks like me in there to give them a hard time to profit. It's not enough to stop me from enjoying my time with others I expect to fight each event. This is about a fun event that is related to dragons(?) being extended or offered outside the usual Canthan New Year, Dragon Festival or redux events since the GW 2 release will definitely impact player participation during THESE EVENTS. Again this is not about the actual game but the events that allow us to play the Dragon Arena format. Clear as mud?
