The CB system protects us from you and you from us. I am a Baron and cannot be ousted unless the Duke removes my title. And if someone holds my seat for 28 days I doubt the Duke will want me as a Baron lol.
As a commoner in a Game I dont understand why you think you cant succeed.
Whats your play style? How will spend your game time? If the answer is you just want to be in charge and point fingers then you probably will never attain such a position as Mayor+ because you wont get the fame, wealth or Rep to do so.
Im a Baron and my personal play style is Adventurer/Smith
so even if I lose my position I will still have two jobs.
This game must be treated like a fast paced simulator, dont waste your life complaining about the rules, instead make the rules work for you.
Pick your play style, link up with a Noble who needs you, gain wealth and Rep then become a Mayor or a COUNT, or a Guild leader. Post launch there will be no cash shop, All the Backers will have spent Expo seeding the world with what they spent real money on, the commoners and new ppl will be able to take advantage of the roads, trade posts etc etc that we the backers put in the game.
You may not start as a leader but why should that stop you from becoming one?
Prove yourself in combat and become a Nobles Champion
Prove yourself a great spy
Prove yourself a great miner
etc etc
Find your place in this world or at least the mail room of where you want to be just like IRL.
