I think there should be an only "FFA" 30 kill challenge because right now most of the maps abuse the capture the flag game mode and make this cat. not very competitive.. Just my opinion. Or even make like a snipers only category :)

I concur. This category is quite meaningless when you consider that the CTF mode makes everything so easy instead of actually playing the game as it is meant to be. I also would like to add that ground rules should be put in place about things like hardcore mode, bot weapons, create-a-class slots, etc.

I think there should have been ground rules from the start, and there should really be ground rules now. Right now the current system is ruined, with maps like nuketown basically being untouchable due to CTF being a viable mode. If it was like how BO3 is for example, with FFA being required and no user-created gamemodes (like hardcore mode or editing things like weapons for bots), then the game would be actually worth running again without it being worthless.

Regarding wasting peoples effort, they shouldn't have been doing it in the first place. It is a broken system and they took advantage of it. If it gets fixed and actual ground rules are in place then those runs should really be removed to allow breathing room for actual non-CTF runs.

Still though, my point still stands. The system they had which is still in place is heavily flawed and needs to be fixed for the future. Without fixes the 30KC can be exploited, thus ruining any competitive aspect to the category.
