Changes to URF there should be

We all lover URF; It's an experience of non-stop action that seems to bring people's limits before the champions' limits, and oh boy it's hella fun. But I've asked myself, what would changes to URF be to make it just a bit better? Well here are my suggestions:

1. Lower death countdowns. When you kill a champion, with your low cooldowns abilities you will be able to end the game quickly and make the game a little short if you ask me. How about a 5 second death count down at minute 40 where everyone gets constant pressure and desicions to make nonstop. I'm pretty sure it would be a fun experience to have.
2. Increase movement speed in boots. Instead of everyone getting teleport in urf, why not increase movement speed in general to let everyone get to their lane quicker. Not to mention the ganks champions will make that will challenge get the skills people have with reaction with escaping or even a counter gank. I think it's a good to have this, because creating such and environment where everyone can move quicker creates a feeling of pressure and adrelalline.
3. Make cc last less. With the speed and cool down that will be added, the balance of decreasing the time for cc speaks for itself.
4. Adcs should be given a 90% cool down instead of 80%, it seems in URF in my experience, add don't seem as much fun as they should be. Even supports become better in URF than Adcs. But I guess, this suggestion is more of a personal thing.
5. Give the towers strenght!! I mean towers in normal games become weak late game, and it's unfair for the loosing team. Come on Riot, make them strong to make the game feel more balanced for the loosing team, especially in URF. Well those are my suggestions. I want to hear what you guys think, and if you have better suggestions let me hear I want urf to be a better game than last year.
