For one i will start by suggesting a key to hide the jousting notification on the side of the screen.
Servers should have timers on the lobby menu to say when it will end. (Sick of joining games with 1 minuet left)
Game should not begin until there is x amount of people inside. (walled off from leaving spawn)
Would be nice to see a weekly leader board / ranking system with rewards so there is more incentive to actually play them as just feels like a chore for military points.
and ultimately more jousting times
