Abilities that's not worth maxing at all?

I mean just leaving it at Level 1, but are there types of abilities that isn't really needed to max to Level 5 at all?

An example I can think of would be Tristana's W since it's really well-known for the jump-resets on kills, or tha all-natural Udyr's abilities where some you may not want to max at all, but other than that, are there any others?
