WHY YUUMI JNG?

Obviously the main reason for this is having fun, please just don't play it on ranked. However, if one or two of your teammates gets fed in the early game, you and the support can help him to get even more fed in the mid-late gamE.

Now is why you should be premade with your bot lane, to gank lanes you'll gank bot lane and try to push the wave as much as you can, then ask your support to roam, you'll get on him and go to gank mid, this is why you preferably want a support with great mobility and hooks, when you get there simply try to hit the enemy with ur Q and heal your mid laner. To gank Top lane both of you (The support and you) have to back and go to top lane from base. If the gank succeeds (It probably will since it's a 3v1) then try to do the Rift Herald or gank mid, then you can clear your camps and he can go back to the bot lane.

In mid late game you will be a second support to the team u will stick to the most fed one on your team and win the game ¯\_(ツ)_/¯

First of all, try to play this when you're a premade team, though with 2 friends that play in the bot lane is enough. The support should have preferably a hook like Thresh, Pyke, Blitzcrank or Nautilus or a stun like Morgana, Alistar
The top/mid laner should have a good level 1 aswell

You will start BLUE BUFF and you will need ur laner to tank the buff for it
becomes half hp then u heal him and complete taking the buff, then you take GROMP > RED BUFF > KRUGS and u cross your fingers that your toplaner cld leash u then you cld rotate to SCUTTLE CRAB if ur team have prio.
Quick Summary: BLUE BUFF > GROMP > RED BUFF > KRUGS > SCUTTLE CRAB
