Soooo Season 3?

It looks like I'll be away from home tonight so I won't be able to play S3 until Thursday 🤨 but I want to leave the game in a workable state for my return.

Am I correct in thinking the operators in my 4 slots will retain the loadout, even if I swap them out for another operator after S3 launches? Any operator added to those slots after S3 will have a blank loadout?

I can swap out 1 skill track of my operators, so for instance I don't have one with Bulldozer, Berserker and Eagle Eye so my operator in slot 4 with Bull/Bers/Tac can be changed to what I want?

Anything I should be considering before I leave home?
