To say to just deal with how the game works kind of defeats the purpose of asking for and proposing changes, isn't it? I am also for changing how the MP3 fights/xp count works.
It's my first time playing this game, and I ended up reaching max XP at 80/86 or something along those lines. It's not only frustrating to realize your wins don't count for your creatures anymore, but also hindering later on in the game. Now that I am MP4, lots of my creatures only need more battles won to be upgraded, but given that I never managed to upgrade a lot of them in the first place, because of the lack of being able to get those wins in MP3, I have a fairly weak army, and so far have yet to win a single fight in MP4.
It's not only a matter of wanting to build a powerful army, it's also just playing the game. For me it is practically impossible right now to find an MP4 that doesn't have tons of strong creatures, high stats and great items and on top of that *doesn't* give me 650 negative honor if I do manage to beat him.
