probably the cause is the recent banwave from blizzard 13/05/2015 many accounts get banned 6 monthWhy are the queue times increasing dramatically - sometimes it takes an hour for a single random battleground.
I'm in a similar situation, being in the Oceanic Realms and the western most part of that zone, and with work in the day I can only get on late our time, which means I'm too late for the Oceanic Realms and too early for the US realms.........
30 - 60 min queues for me also, and there is nothing I can do about it........
except maybe some exciting fishing or archaeology :O
Keep in mind that this bracket gets AV pops.
If there's an on-going AV match; que pops will slow down. And then again a lot of people don't que AV for their own reasons, similarly people don't que WSG(premades mostly que WSG). Meaning some people may only que for AB/eots.
There's a lot to keep in mind when asking yourself why ques are so slow. A lot of it can be explained by what time of the day you are queing up and what bgs are you queing up for.
