Hi, new MP player here.
I've played about 20 so far, lost about half, won a few, the rest were incomplete. As far as I could tell, giving a unit gold/gold upgrades is exactly the same as giving it 3 bronze chevrons in terms of cost and effect. Aside from the fact the you could adjust the upgrades according to the situation (for example I would probably always give Spartans gold armor but no weapon upgrades), and the small chance that your units will gain exp in battle, is there any difference between the two? Say if I want to give a Companion 3 upgrades, is there different between giving it gold/gold weapon/armor and 3 exp?
Thanks!
