I am 100% for anything more than 24 hours. The argument "this is a hardcore game" is the mentality that many private servers have and the reason many of them fail. IMO, MMORPG's, This one included, thrive with a balance between "hardcore" players and "carebears". Otherwise, you have the 30 sweaty neckbeards controlling the server after a couple months and everyone else quits, and the servers lifespan is drastically reduced. My personal hope is for us to have a well-rounded version of archeage for a lot of different folks to enjoy, not just the sweatlords.
The majority of this servers initial playerbase will likely be veterans who are all now in their 30's, 40's or older and cannot no-life the game anymore. Personally, I wont be able to play a fraction of the time I used to and I'd imagine i'm in the majority.
