That second list of champions is definitely low skill floor, but they are not that low on skill ceiling. I know for a fact two of those champions see active play up into diamond.
I'm fine with the new champions and their design, however I hate it when people decide that the past should be left behind when older things are still good now. It shouldn't be out with the old/in with the new, it should be out with what doesn't work/in with what does. Just because something is old doesn't mean it no longer works, which appears to be what you're saying. Perhaps Riot is actually doing this, however you don't seem to be of that mindset. It's not a matter of nostalgia, and I find your disregard of anyone who would disagree with you insulting.
Mobility creep, however, is not a good thing for one simple reason; there is no built in end point. The whole idea of creep is that it spreads to no end, which would result in current "mobile" champions needing reworks eventually because they are not mobile enough. Mobility is not the problem here, it is that mobility appears to be increasing in a way that will narrow the amount of creativity people can put into their strategies.
Now, I would argue that faster pacing actually reduces the overall skill cap. Look at other MOBA games that are designed to be fast paced. The main one I have experience with is Heroes of the Storm, and while it is indeed fast it is also almost always a stomp in one direction or another, with small chances later on for a single team fight to turn the game. Team composition matters very little over there, with the only real difference in win rate being teams with a support vs teams without one.
In League, however, team composition matters greatly. There is a level of strategy in it that adds to the amount of skill one can gain. Sure it slows down the game, but you can't just have both because you want it. The slower the game is the more positioning matters, along with body blocking, peeling, and controlling areas of the map. The faster a game is the less these things matter, and the more "killing your enemies" becomes the main strategy. I might actually be fine with faster paced games if people would just understand that you don't have to kill an enemy to beat them...
TLDR: If you want high skill caps stick with League or DOTA, and if you want fast paced go with SMITE or Heroes of the Storm. There is no need to insult people for wanting something out of a game that you dislike, and there's no reason for you to want a game changed if there are other options available that better fit what you're after.
Also screw mobility creep and every other type of creep besides difficulty creep.
make for a much more dynamic, fast paced and higher skill cap game. With these champions your choices matter ALOT, and there is a clear difference between people who are good at them and people who arent.
you have bad tastes and there is a reason why you are not a video game designer. Nostalgia be damned, lol is a growing game and you don't grow by copying the past. Mobility creep is a good thing, it shows this games development into something better than it was in the past. Instead of dumbing down new champs riot should continue reworking the old ones into things that better fit their new design philosophy.
