You are wrong.

There is no way the synergised team would win..

This 200K BP difference would make it impossible. When the dude with the 600K will strike you, its gonna really really hurt. and half of both teams will die.

Ive been in that situation multiple times with less difference than 200K and it turned out to a loss.

And believe me, my setup has alot of control, support, defence and dmg.

You are just simply wrong on your saying or being delusional.
