you cannot launch a product that is labeled "Quality" before it is ready, it is what happened to every other private server out there. Few players will start searching for bugs without reporting them and when they find some beneficial gold or xp exploits they will camp it as long as it lasts.
The bugs would be fixed once known of ofc so it wouldnt turn out like Feenix where even know you can bug boost yourself from lvl 25-43 solo vs lvl 38-41 enemies... there are even still bugs where you can farm some specific lvl 15-20s and gain 38-50 green/grey loot.... a month ago you could repeat a non-repeatable quest over and over that took 3-5 min. to do... multiboxers made a ton of characters and moved forth and back earning free gold.
I am equally if not more hyped to get started but i know you cannot risk releasing something before it is fully tested and where the worst bugs, exploits and also hacks have been completely annihilated, if you want to speed up the process then apply as a tester or if you know your program/scripting stuff as a developer.
Note: the 75% does not reflect the servers current state at all since it is only updated once in a while, it is like evaluanting when an becomes completely ripe... so it is impossible to be accurate on it but you can say when its started to get color or give a long term estimation.
Also if you want to make sure the server is better or lives up to your expectations then you should definitely sign up as tester since the developers are focused on fixing and only test what has been tested and proven a few time's.
The more who test and find solid proof on a mechanic the more they can focus solely on fixing :wink:
Or you could try read how addons where made in 1.12.1 or imitate those made making your own or combining some, it would definitely improve the experience for those who come to Kronos having unique, improved or new addons only to be found here :smile:
