What do you want to see in LoL?

Shadow Fiend looks like the hero Nasus was originally based off of, so we probably won't see that considering beta Nasus doesn't exist.

You must've misunderstood, i don't want a shadow fiend.
I want a high risk, high reward, high skillcap champion

A shadow fiend who doesn't know everything there is to know about razes isn't scary at all and will be shut down regardless of how good he normally is as at playing semi-carries.
That's the kind of champion i want. If you don't know how to use it to the fullest extent, you wont be able to play it at a niveau that is going to be useful.

But i suppose that would be deemed anti-fun. Morello doesn't like invoker, after all.
