When it comes down to it, In my personal opinion I believe Kronos should be launched within the month, or sometime early-mid February. Why? Simply because at this moment and time you have people posting often, asking for updates, videos etc. The community is striving and has gained some numbers over the past few months. Now, if you were to release it in Jan-Feb you'd have this community and only room to improve. Yes it may not be as polished as you want it to be and trust me that sucks, but it seems like spell problems aside, the bugs are all very minor, making them fixes that could totally be done when the project is launched, and done well considering you won't have 7 pages of people asking for a release date and complaining about an update they asked for.
Now, if you move into March, April and May release dates, I'm not one to say you'd lose some of the fan base/community, the dedicated will totally stay. But those feeding off of hype will drift off and go play who knows what. I'm not saying it'll happen, but it is a possibility.
Anything past then will really be like pulling on a rubber band, might seem okay but the moment it snaps it is just upsetting. Releasing it in say early summer might actually be a good idea considering it's summer, but that is just a very, very long time away, and a dangerous way to go.
Either way I'm stoked for Kronos and vanilla raiding and all of that good stuff. This is a very long comment but I just wanted to get my opinion out there instead of just ranting or complaining like some people.
