Some changes I would like to see

We should have an official role trading option in champion select. Kinda like how you trade in ARAM, except for roles. This way, if there's ever going to be anything like dodge if your jungler doesn't have smite or force the jungler to take smite, the client can easily tell who the jungler is. It'll also clear up some confusion about what role some people that are premade are actually playing when they trade while talking in some 3rd party program where you can't hear them.

Please add another counter for how many more keys we can currently earn. Chests it shows you how many more you currently earn, and when you'll be able to earn more. Keys you could have maxed out and not be able to get any more, and it doesn't show you, nor does it show you when your key drop rate will reset again.

Buff the support role. Support mains don't like being so weak, and other players just don't want to play support or wait so long for queues because there aren't enough support players. And the planned reduction of global gold on towers next patch is particularly worrisome as supports will get even less gold. They aren't even supposed to take a part of the local gold from their ADC so they likely won't even get a piece of that.

Can we just prevent people from buying items that don't stack? Like limit players to 1 boots, 1 dark seal, etc.? I swear ever time I've ever seen someone stack these it's been a bad build and I've never seen multiple boots actually be an effective build. It's mostly just to get rid of some really stupid noob traps or careless mistakes.

Make it so that ARAM is random of all champions and not just the ones you own or are currently free to play. I find it kinda dumb that I'm not buying a lot of champions because I don't want them to be given to me in ARAM. I'm probably just never going to buy more champions, except for newly released ones, unless this is changed.

Go back to the old respawn timers or at least closer to them. They're way too long in the 20-30 minute range and promote way too safe rather than going crazy making big plays trying to get objectives gameplay are and far too punishing to your entire team just because one player gets caught. And it's just really not fun for your whole team for that 52 seconds one teammate is dead when you're not even at 30 minutes yet.

Maybe more but my game started lol.
