Problem with upgrading to additional units
I've had a problem lately, where when winning a game pretty well or in a dead even match, upgrading to priests too soon, ends up actually greatly increasing the level of my opponents, or making their war rank shoot above ours because they are getting more kills. Does anyone have tips on when to upgrade to priests, etc.? It's just kind of aggrivating buying something that is supposed to be an upgrade and then it ends up backfiring, or so it seems.
