Competitive games are what I yearn for in the 39 bracket. The most memorable games are ones that aren't just rollovers that end within minutes. 60 PVP is set up to have the full premade tactic and if you queue with a small group, you're gonna have a bad time. I'm sure a lot of people come to twink so they can avoid that, but it seems that 39s is getting closer and closer to the 60 bg mindset.
In the west, everyone knows that the main alliance hub is whitemane. I even have a 39 hunter there myself. The problem I have is that it seems that in all hours of the day, there is sizable premade going that plagues the 39 battleground bracket. It can be 9am or 2am and it's going.
Horde have a pretty bad queue timer compared to alliance, we all know that. The last thing someone wants to go against is a dominating premade vs their pug. I personally wouldn't want to wait 30 minutes for a queue only to be graveyard camped due to being outnumbered.
We've had the East/West split which hurt queue times by quite a bit. People believing that it'll kill the bracket. Want to know what I think will kill the bracket? The constant 8-12 man premades that happen every day, throughout the day. I've already seen plenty of messages of "X group is queueing, guess it's time to stop playing".
I am here for the competition, that's what I want for the bracket. What isn't fun is getting into multiple games that are so one-sided, you can't do anything but be a honor punching bag.
I want 10v10 premades. They are fun to play and watch, but it's often not worth the effort if the general gamemode is riddled with giant, 10 man premades at peak hours. It'll only get worse as more people migrate to west to join the most dominate alliance guild when it comes to numbers.
This'll probably go on deaf ears, and you may think "you need to suck it up", but most alliance twinks only see their side. It can get pretty bad over here on horde. To the point where you just don't want to queue anymore as you can make better use of your time.
TL;DR - It would be cool to get more competitive games against other players, rather than straight dominate, impossible to win ones.
Edit: I personally think the problem isn't the premade itself, but how often a giant premade is going. That I don't find fun on both sides of the spectrum.
