This is pretty similar to my experience. I don’t consider this toon a twink since it’s my Classic main and highest-level character, but I was easily able to get the BoE’s and most of the dungeon gear/enchants and maintain consumables on my own through normal means at-level.
I suspect there’s slightly more Horde twinks overall, but there’s some great Alliance players too, and if you’re willing to play a longer game, no team is ever really out of it until the last flag caps. There are plenty of players on both factions that can change the game if they sub-in or show up late.
There are some lop-sided games, and late nights will see some 10v7, 10v6 etc, but many of the players I’ve seen aren’t afraid to deal with that, and I’ve seen several of those shorthanded games get turned into awesome victories. I feel like this bracket has a higher percentage of good games than anywhere else I’ve played.
