I like i can induvidually upgrade my units - but it gets to a blob when i am running a party with 100+ and after each battle need to manually upgrade all my units - Gets even worse when you run a party of 200+ and only got tier 1-2 troops that needs upgrading after a battle
Maybe unlock a perk which enables a button to auto upgrade your units? Something like that - Could be a perk at 150ish Steward
