While I do believe that unintended class runs need to be nerfed, I don't think that doing it for every map would be fair. In my opinion it's best for either the community or those who run Tempus to decide. While I don't think that it's the most feasible, allowing the community to vote would likely be best. However, I don't think that we as a community would be willing to evaluate every map and make a decision. Perhaps if there was a streamlined system for it, then it might work. Although, as it stands with the forums at least, I don't think that it'll happen. It'd probably be best just to leave it up to those running Tempus.
To expand on why I don't think it'd be fair, consider jump_lanc. For soldier, it's not crazy, and it's really more of a technical map that could have honestly been intended for soldier. Lanc doesn't have random bhops, and isn't just wallpogo for 20 minutes in a straight line. In contrast, maps like jump_storm are just endless wallpogo, so there's nothing interesting about the map. The majority of people only play maps like these to gain points, not to have fun jumping. It's just another map in the endless, unenthusiastic drudge of getting decent completion. Maps like Storm, that only exist for points, are what need to be nerfed.
In the case of soldier:
While you could argue that you in particular think that wallpogo is really fun, and thus demo wallpogo maps shouldn't be nerfed, I think that looking at it that way is selfish and inconsiderate of what other people want. It seems like most people don't like wallpogo, so why make them spend hours grinding maps that they don't even enjoy? Try to say that nerfing demo maps will "kill" wallpogo, but it won't even do that. All that you'd be fighting against by supporting that idea is that jumping and competing on Tempus should be fun.
