what is more troll alistar jungle or rengar support?

Both are actually viable up to Gold ELO

Well with the changes in S5 Alistar Jungle actually works again, but I don't see how Rengar could support in any way or form.

Alistar can't clear for his life but at least his ganks are good.

If you ever try Rengar support in ranked I will report you.

Rengar ADC xD

I used to play Alistar Jungle, so Rengar Support is more troll.

rengar support is much more troll. alistar is actually a decent jungle.

Alistar was a meta jungler for a long time...

I've seen rengar support beast though bot lane.... but usually the rengar isn't support for long.

Alistar's passive used to deal double damage to jungle creeps, until they were forced to take it away. Alistar jungle is a thing; it's just not meta cause there are better junglers.

Rengar support is pretty bad... no farm=no damage=no Rengar. Would only work if you got really fed, which in most cases means any other support would have worked just as well if not better.
