Well, aside from weekends night time in EU is rather dead, no use sugarcoating it. Folks gotta sleep before work and stuff. Usually takes me like 5-10 minutes at best during prime time to get a random normal bg (6:00 - 8:00 PM, give or take)
Yeah well, Maintenance day is on Tuesday in the US, Wednesday in EU usually between 3:00 - 4:00 AM.
If you are more active during night hours in the EU and you are PvP focused then yeah US region might be a better bet if you can stomach the high latency.
Try Horde. We are currently the less popular faction and our queues are typically shorter plus you get bonus honor often. You can try merc mode if you wanna stay Alliance. From 9PM to 2PM you can get into rounds anywhere from instantly to 5 mins on horde.
I think people just enjoy BG blitz more and queue for that, since it’s faster and combat is less spammy/healer centric it’s just easier to grind, regular bgs get very tiring fast when you mostly sit on a point and a bunch of casters and healers just spam AoE at eachother for 10 minutes straight
