Сonstant auto-filling of squads before battle

I can't think of a single scenario where the autofill is helpful. At the very least, it's annoying and a waste of time. And it's occasionally caused me to take the wrong characters into battle (sometimes wasting energy or attempts). 

Even for a very new player, the autofill is generally not the team they should be using.

(But keeping the last team I actually used is good [like with raids]. So don't throw that out while removing the other autofill.)
