Gym has an annoying 'bug' or design, where someone can shoot the ball up to the stand and it stays there.
Or people can boost up there ... and stay there.
One player doing this ruins the game - and everyone leaves.
This has been my experience every time gym has been played.
And there is absolutely NOTHING wrong with pillars in maps.
Orginal tribun was perfect. The pillars add a block between you and opponent which equals 'variety'. Form your own tactics to use the pillars. Throw in that you can jump off the pillars to create super height jump shots... = good.
New tribun is too large though. Completely lost popularity here in Aus.
Replacement map.. anibus? has taken over all tribus playtime. Its the one with the two pillar rows and the static mesh statues behind goals. Map is fun to play.
It is not perfect. The penalty box is raised in n00b mapping style (what I do), because the mapper used a cube as the penalty zone, not a surface.
But is fun. Pillars add variety. You use the pillar to create space.
There is still backwall space. Size is nice etc.
Pillars are good - don't dis the pillar!
Here is Aus - we want maps that are 'in-between' small cube and cube.
Currently every map appears to be cube sized... or changed to cube size. This is too big and makes for slow boring gameplay, especially on publics. We want fast gameplay - hence sprint on

- that ain't always as spammy as smallcube.
Mid-sized maps are the most popular here - and we have to look to customs for that.
