I think we all need to hush and let Nexon try and make this game better for us to play. Sure we have our opinions about this 'nexonfail' but unless you're a member of Nexon and program it to the point the game is in now then you can't say anything. You're free to rage about their fails but most people don't like hearing other people "QQing."
Nexon made such a long Maintenance to try and fix the bugs and glitches that we all know we have. Longer mainteance means they haven't found a solution yet and may have another possible solution. Then you also have the problem to get the server live as in bug fixes can be altered when the game goes live. Bugs you can live with and bugs that you can't live with are two very different things. Nexon will deal with really bad bugs first like the massive lag that caused a 1 hour maintenace last sunday and things like we're experiencing now can be left while a complete dianostic of the bug/glitch is made and a proper 100% fix solution is found.
If you think that new content is 'just added' to the files then your wrong. Its like a jigsaw puzzle, if the new puzzle pieces don't fit with the old ones then its going to be broken and that is what is wrong with Mabinogi to my understanding. You also have the possibilities of Nexon's 'Pro' Programmers working on Vindictus due to it being a new game, and a new game with bugs is a game no one wants to play so it comes first.
And mabinogi being down for 12hrs? Lol, thats not going to kill you.
