Ideas on making TFT more balanced and fair

There are a lot of problems I've seen when the game relies too heavily on RNG so here are some ideas to make TFT more fair and balanced:

• Make it so everyone gets a specific number of items in every PvE round, what items you get is RNG. (Playing against a team with 6 complete items vs my single incomplete item)
• Refreshing units make it so we are SLIGHTLY less likely to see them again on the next re-roll (Playing against 3 lvl 3s mid-game vs my group of lvl 2s and 1s)
• Shorten CC duration or implement a tenacity mechanic for all allies when going for a certain buff (Playing against 6 glacial or other cc unit almost perma-stunning everyone)

These are some of my ideas so they may not be perfect but just throwing these out there.
