Patch will be done when it's done If you think "oh my god, why do I have to wait another 2 hours" keep in mind that we in EU have to wait for another day
another day +2hrs calling it
Usually they "learn" from what the hold-up was on US and EU is done more or less on time. Not always, but sometimes. Let's keep fingers crossed. But to be honest, isn't at this time 90% of the playerbase season only? So until Friday evening everything's just meaningless anways
If you're super excited and you want to pop in as soon as 2.3 goes live, in the past when they've extended maintenance by a few hours, they sneak it up after only an hour or so. So it pays to keep your eyes sharp.
It may also go up right at 11 PDT or it may well be extended. There have been times where it gets extended by several hours.
Either way, lets all be cucumbers as play it cool, aye? I feel for my European brothers who have to wait much longer.
