@Omni-Triforcer Honestly, every one of the shows has had comedic aspects. Nobody wants a comedy-centric version of a show that was never comedy-centric. Sure, different versions of the show have had varying levels of comedy in it but then you get into what kinds of things people consider comedy to be, and that's kinda subjective when you take into account people's preferences.
I think the general consensus here is that people don't want one that has a focus on comedy instead of the story. All of them have had action and whatnot, but I don't think there's ever been demand for a comedy-centric Ben 10 show.
Whether or not you should be nervous about that idea being tangible, well... I should probably say whether or not you decide to be nervous about that idea being tangible is up to you. Whether or not it's an actual possibility is a very different story. CN (which is a collection of different administrators overseeing a collection of different creators with a collection of different staff members) has a track record in terms of reboots which, at this point, has not been savory, but the subsequent groups under CN (admins, creators, staff,etc.) have different individual track records. These individual groups come together to make things that the people in charge of deciding whether or not it airs have more of a managerial role than an absolute final say like people tend to think.
Basically, CN is a bunch of different things and shows don't come from the top and trickle down, they come from one layer that another layer takes care of and are overseen by the top layer, and the top layer makes minor changes. People come to them with ideas and they help the people to make the idea tangible. If you're worried about Ben 10 turning into an equivalent of Teen Titans GO! you shouldn't be questioning CN's track record, you need to be questioning the track record of whoever is coming to CN and wanting to make it happen (that being MoA).
