Btw, I noticed the squad set up you posted was your #1 set.
Since your 1st squad will always be your helper squad, you should organize your set #1 by highest power, so your first squad is the most powerful possible, which will help your in-game friends out.

Trying to balance out squads' power and speed is the best way to go for your everyday usage set, but do that on your set #2 (or whatever other number you prefer)
