I don't think this is a surprise but the AI is currently completely and utterly broken.
So many times champions don't do anything or they path al around the map instead of going straight to their target.
It affect ranged less because they usually still attack enemies in range but melee simply stand by and get his while they don't try to move nor do anything.
I honestly prefer PBE because it has a lot of improvement compared to live version but that simply makes the game unplayable. Almost EVERY, SINGLE fight has AI issue.
Post your PBE bug reports here: something not functioning as intended? Store is broken? A champion's ability is not working? etc
