Also having a higher MC (and yes strength) player, makes for easy kills, 3-4 people can make a quick gank on someone and run away. Anywhere you might have 3-4 people punch a single person, just delay it long enough for the MC guy to stack 2 coins with call down, then sting instead of punch. At this point in the game he can probably sting through 20%~ and still kill someone. I'm kind of surprised you're only aware of this now, it was being used for a good majority of last world.
I referenced this in regards to that time 4 people form Portgas's village ran away from Jiochan, claiming more people were bound to show up. If you have that high MC player, stack those 2 coins while running, turn around and try it. If you don't kill the guy, just clip him and keep running. This will only take a minute to do~, if it was me in Jiochan's position, after someone had the 2 coins, I would back off and not risk it

You may have foiled the plans of BAD-EVIL this time, but there is no rest for the wicked.
