I don't think Mullich is more overpowered than Brogh or Tirakors. And Mullich +1 will be a decent hero. Especially considering that you can't choose him during map generation.
And you can make Roland a specialist in "pokemon."
I wanted to make this suggestion a long time ago, but I kept forgetting. Sometimes I just want to play without limits in Warlord mode, so I suggest bringing back the "Wild Monsters" checkbox to play with diplomacy.
Oh yeah. And also, definitely add a golem niche.
