A significant portion of the map pool is noticeably bad to terrible in 64p.
Bridgetown is a solid worst map in the entire game in 64p even above some of the TDM maps which is a serious achievement.
Thayic Stronghold has been a dogwater tier map from day 1 and nothing has changed. It's sad because Stronghold has tied for the worst VIP objective in the game, yet it has the only good VIP in the game.
Both Tenosian maps aren't particularly fun to play on either side either.
Aberfell is the best of the dogwater tier maps, yet it's still riddled with horrendous geometry, terrible ground clutter, and the worst VIP objective in the entire game tied with Argon.
If you've ever noticed a stupidly high rate of queueing into these maps or into the segment of the rotation which turns into these maps, don't think too hard. The answer is that players leave when these maps show up. Players don't like these maps. More open slots means more slots to queue into proportionally which means you're just literally statistically more likely to queue into those maps just like defense.
If these maps are so problematic that people leave when they play them remove them from matchmaking until the maps are reworked to not be dogwater, make a queue without them, or let us choose not to queue into them. It's simple as that.
