I understand that the basis of the game is that you are a captain of small "mercenary" force helping the faction you choose, so it's normal that you aren't as powerful as the main armies. But there has to be a limit, if your company of soldiers have a maximum around 50 (well, you can raise it still more with renown until infinity, but that would require infinite time, 50 is more a realistic number) then the maximum of the NPC armies should be around 200-250. 4-5 times more, so there is still armies you have to run away when you see it, you can't fight and win against everything, but it wouldn't be so unbalanced.
