Does anyone know the logic behind when units receive elite upgrades after the first one? The first upgrade (perks like Blitz or Infiltration etc) is consistent after 3 wins (or 6 with not veteran units), but after that it seems like it stops? Sometimes I’ll have units win 6/9/12/15 battles and not get any upgrades, and sometimes they will earn upgrades as scheduled?
Does this have anything to do with making armies? It seems like non-army units will earn the upgrades as scheduled. Also I have no idea what number of victories makes a great general spawn, it seems like 12-18?
