Back in TBC waiting times to get on our realm (Hellscream Europe) were anything from 15-40 mins at peak times - I'd happily accept that tbh. I'm sure those on realms that waited 2 hours plus wouldn't and that's fair enough - but that's what balancing the population is about. Of course they could develop something akin to GW2's overflow servers which are working very well indeed. Heck they'd probably have enough server capacity left over from shutting down the underpopulated realms to not require any new hardware - just reconfiguration of the existing architecture. But I guess their dev team is now so small that such a grand project is just out of the realms of possibility, sigh.
