well you could always just cheat if you don't wanna grind for trade... there is also a mod which allows you to rebalance XP gain from mod options. those will fix your issue for now.
I was rude because in my first reply I showed you the issue with your suggestion, and I asked you questions to help you make a better suggestion. but instead, after you make a lazy suggestion which doesn't work (too much clicking for upgrading units), you reply with "I feel that doesn't matter for the way I'm playing, so ill just make a statement as if everyone cares about the same things as I do"
yeah but you forget your own suggestion. you're saying locked horses should not be used for upgrading
Oh you feel like that? You feel wrong.
I don't complain Any suggestion I've made or will make is because I want to contribute to improving the game. don't take it hard.
What's your suggestion?
I'm gonna assume you replied to the wrong thread by mistake.
