Champions with ultimate that are not priority?

Another example is Jayce. But with him it is the same as with Elise and Nidalee. A boost in some defensive stats. The difference between these 4 champions and Udyr is that they get their "ultimate" at level one where as Udyr does not have an "ultimate". He just has 4 spells he can freely choose. Thus I would say Udyr is the only champion who can get away with not leveling his "ultimate".

I would say these three, going on a very thin argument that they aren't exactly essential:

• Elise
• Nidalee
• Karma

All they really do is boost your stats, which yes, could be argued that it's not a priority, but it's too beneficial not to have it.

After putting one point into Tryndamere's ult, some players avoid putting more points into it, since the difference is very minor.

The only benefit is the cooldown (-10 seconds) and the fury gain upon activation (+25). The duration remains the same.

If your ult has a ridiculously long cd, and you've just hit level 11, I'd delay putting a point in it so long as you're ahead as by the time it's of cd you will have probably levelled up again. (note that this is only when you are massively ahead and levelling is a guarantee.
