My biggest pet peeve about updates is when the come out when I least expect it.
Take these new nice/naughty crates, for example. Now that I have a good feeling that very valuable things are bound to come out of them, I have an urge to try and open one. Only problem is that I need to get one without having to deal with the pitfalls of trading in case I happen to be wrong. And since I'm at least half way through the drop week, I can't get a headstart on amassing them.
That, or I don't have enough crafting material to try and shoot for a low craft number of something.
