as Irelia, both jungling and laning.
Is it possible? If so, on whom, and when should it be done? Any tips/thoughts?
Have your jungler, or you, buy a lantern and ward your jungle. Often times they'll cross over and you can gank them as a team if you act quick.
You don't need to do much to counter jungle... Just go in and steal as many of their creeps as possible while leaving one small one behind at each spawn.
Now they lose massive amount of Exp and gold.
If you want a jungle gank, then you need wards at the buffs and Dragon to kill them off.
