Honestly I don't think you are being fair bruisie. Yes Jooky should have been better prepared and had been more on the ball regarding the servers capacity but being surprised with hundreds of new pre-orders (a significant % of the population) is a reasonable hiccup to encounter. It is also worth bearing in mind that there is nothing that properly simulates the stress of release day on a game like this, no matter how you prepare for it you will discover quirks in how your code responds to massive pressure that were unexpected. Virtually every game has this problem for precisely this reason which is why you get things like the 'pre-order early access' program so that it can clear these problems up during a period that is justified to have lower performance because 'we aren't paying for the game yet'. Lastly, Jooky isn't a network engineer and has been open about this being one of his weaknesses.

Give him a chance to figure out what is wrong and fix it, because it is more complicated than waving a magic wand.
