I'm currently trying to beat the Bulgarian 1st UHV on Monarch and it's making me

It's like France on Emperor. Some things are really off-balance:
* Serious stability problems. Several times Odrin (Hadrianopolis) has declared independence in my games.
* The Byzantines can buy mercs all the time, but the Bulgarians have no mercs available for hire at all. That's unfair.
* If most of your Konniks are getting wasted while attacking the Spearmen in Hadrianopolis, who will be preventing the Avar barbs from pillaging your improvements and razing Preslav?
* Who will escort the 2nd Settler to Macedonia or Arberia if most of the Konniks are getting wasted?
* If you don't attack the Byzantines early, you'll be confined into a quasi-OCC mode where you'll only have 1 city that can slow-build military (9 turns for a Konnik

, with Horse, Iron, Cow and Wheat). The other city has to train a Settler for either Macedonia or Arberia. Maybe additional Settler at start?
* Why do Bulgarians have to conquer Arberia anyway? Seems too far away from historical Bulgaria. Is it historical?
* Serbia is pretty much useless province for Bulgarian 1st UHV. If you capture the independent city that would spawn there, it will revolt and declare independence again.
* Konniks are too expensive to build
* Magyars spawning 3 Horse Archers NE from Preslav in one turn
* Archers are overpowered and Catapults are underpowered.
* Reducing Constantinople's defenses to 0% with Catapults would take ages. Even then the capture of Constantinople would be a pure luck. Btw, I only managed to do it after I had added 5 more Konniks for Bulgaria in WB.
I have also attached the impossible save from the turn when Bulgaria spawns. But be warned
