The only reasons CRZs bug me are in relation to pet battling/collecting.
Rare pets are hard as shit to find and rare versions of rare pets are just ridiculous because there are five million people camping for these pet spawns.
There is a pet that only spawns at 12:00 midnight, but every time I go to that zone, it's not yet 12midnight because I'm being CRZ'd into a realm with an earlier time. I really can't stay up until 3 AM just to ensure that whatever realm I'm being put into is at midnight. It's apparently supposed to be up in the morning too, but because people are farming it or maybe I'm just ridiculously fucking unlucky, I've never seen it.
Other pets only spawn during certain weather conditions, and you guessed it, weather conditions change per whatever CRZ you get forced into. Going from one subzone of a zone to another subzone can change the weather.
The only problem that is at all justifiable is the first one, which I understand and can accept but is still fucking annoying. The other two, however, are fucking retarded. Seriously just fucking retarded. I can't tell what the time is or what realm I'm in and I can't guess if the weather is going to change the second I enter the area where the pet I need is.
I know you can manipulate the realm you're in by getting into parties with people, but I don't have friends.
