Is playing Jungle in URF bannable?

It's definitely not impossible, but due to how not every champ benefits as much as any other in this game mode, there's too much risk. Not to mention, players have no choice in their champions, so if you deliberately leave a champion that doesn't benefit as much from urf mode as the enemy he/she faces, expect to see results not in your favor.

URF is designed to be a mixed bag though. S'long as it's feasible, we play what method we can find as something that works in the mode. It is what it is.

It isnt bannable, but leaving one guy to lane by himself vs 2 cancer opponents isn't very nice.

That's a tough question since tactical disagreements isn't supposed to be bannable according to the rules, yet there have been cases such as the nunu support guy that got banned anyway.

It's not bannable, but you're a huge jerk if you do it.

would i ban you? no. will riot ban you? yes. why? because you're getting reported. a lot. supposedly. is it a permanent ban? not likely. have fun playing ivern without jungling though.

It's not bannable. I've had my share of players flaming me over having Smite but I never really jungled in the first place; even had one who said if you don't take you deserve to be perma banned.

Realistically, I don't like carrying given both its cooldown and its brief reliability against spam level champions. All I ever really do with is buy Hunter's Machete at the start, get an early lv2 (which kinda matters on some champs), and then let the game play out as normal with the option to siphon health and gold off the jungle if need be. Not everyone gets that though and will just assume it rather than using the knowledge they know about the game.
