I thought game modes like Ascension was meant for fun
Apparently, players who still pick 
didn't think so. Fking try-hards.

Have you considered that they might find those champions fun? Or is only your fun important?
One thing to keep in mind with a temporary game mode is that the champions are balanced around the normal map so if you're playing one of the seasonal game modes you should be more focused on enjoying what was created.
Also, if you're focused on winning if you can't beat em, join em. Every mode has a meta.
Personally, I feel that every rotating game mode could be improved by the ARAM model. Your champions are randomly selected. It would be more fun overall... but I'm not a game designer or balancer, so, I don't know :3 I mean, it definitely felt like an improvement for URF when they released ARURF a few months back.
