I Think URF Would Be More Fun Without Teleport
Teleport isn't that fun, basically you just have 4 teleport spells behind you and 4 from the enemy team any time you are trying 1v1 someone and it ruins all of the fun. There's no down time because of teleport and basically even if you punish your opponent they just teleport instantly back into lane before you can do anything. Champions with a large amount of CC like Alistar also have a pretty huge advantage having teleport because they can just keep teleporting to ruin any engage that happens.
URF would be way more fun if there was no Teleport.
