Getting rid of natures and EVs, and replacing them with AVs which is basically like how EVs worked in Gen 2 where there's no caps and you can just max out all stats, is fucking cancerous because it encourages competitive play to be all about extremely bulky mixed tanks since there are no tradeoffs anywhere.
IVs would be the simplest fucking fix though. Theoretically when you transfer to the next game, all your pokemon get boosted to 31 IVs across the board. Everything now has 31 IVs, bam, done
