We have merc decks where we mix and match loadouts, trinkets and skins to customise our mercs, why not have a 3 merc squad lineup for easy picks on a map we join?
Things like:
1 Medic, 1 Fire Support, 1 Objective Specialist for flex players
Phantom, Hunter, Vassili if you’re joining a team of noobs and you want to be playing as noob as they are
Sparks, Sawbonez/Phoenix and Aura if you’re all about healing and reviving
Stoker, Kira & Arty if you have to ensure that the EV gets hurt
