Yeah, sorry, mate, but Cross-Realm was a dreadful addition, particularly on roleplaying servers. It was already difficult enough to handle the yaa-hoos and lolboys bumbling through, after Cross Realm went live, there was sodding nowhere to hide.
Of course, Blizzard has always treated their RP-servers as a mistake and a secret shame. Introducing some poisoned saltwater into that particular ecosystem was probably intended.
Cross Realm Play was fine when it was connecting players between servers for raids, dungeons and the like. Communication took a hit, but the cross realm system suited the instance-structure, since it's an isolated location. But it was not a good idea to introduce it to the overworld. Particularly in a way that made people pop in and out of it. But then again, why worry about the overworld?
You're not supposed to be out there, evidently. You're not supposed to be out on adventures. You're not supposed to gather some friends you know and travel to a dungeon, killing some rare elites or ganking someone. Or God forbid, grill a few pretend-sausages over a pretend-fire in a pretend-forest. The moment you're level-capped, you're finished with the game world and don't need it anymore. You're evidently supposed to sit in the capitol and wait for a raid, like an airport, save a few carefully planned excursions for dailies and mats.
The Garrisons seems like the logical final expression of that design philosophy, a place to sit and wait for random raids to pop up without having to spend time around other players as bored as you. Players that flutter in and out of your existance like phantoms, players you'll never need to know and never will. Sometimes it's possible to break through the glass box, as it were, and make consistent relations with other players, on your server server or other, but it's hardly the intention, it seems.
The intention seems to be for us stalwart heroes to sit in a house waiting for something to happen.
I am being hysterical, but that was the feeling I got towards the end of my WoW-experience.
