3 hours of weekly maintenance is standard in pretty much every mmo. Sometimes maintenance is skipped during weeks when there hasn't been much traffic, as was the case a few months ago before the expansion hit. And maintenance is almost always going to occur after major new content has been released, such as the content we have been getting over the last month.

Now, why they waited three days to release the god awful red script system in a separate maintenance from 3.05 is beyond me. I'm actually wondering if someone realized how terrible it was at the last second, and tried to alter it to no avail. Almost like when you're writing for school, and you realize the paper is going to be really bad, so you ask the professor for a three day extension, and yet you still turn in a stinking pile of garbage.
