Races definitely. The ones where you just set a course on the map and people gotta do laps or a sprint. I like the ideas of specific weapon 1v1s.
IMO LMS/TDM and any event with "Chicken" are shit events. They are 100% cheatable and you can litteraly not check that. Especially the Chicken events where the hosts are 100% of the time biased. And don't tell me I'm wrong lol, I've witnissed it almost every time I have been at one.
