I'd disagree with the upgrading of troops, its essentially there to stop a player from having a massive, top-tier knights that will wreck any formation, any faction, any troops, any day of the week.
I usually stop upgrading when I reach man at arms tier. I feel that they fight the best for the money invested into them. The rest of my high tier troops I take from exiled, robber knights and dothrakis.
