20 cities per an account?

I think 20 cities is a little much.  Especially with an alt 40 cities.  And if your sitting for someone on vacation now 60 cities possible.  

Participation in the Broken Lands is entirely optional.  If you don't want to manage those extra cities, no one is going to make you.  When it opens, participating in Elgea will be entirely optional for new players.  No one will make them take on the extra towns if they don't wish it.

One of the things I really like about the game is that I decide what I want to do.  I could refuse to build armies, additional cities, kilns, diplos or anything in the game if i desire to do so.

I think the game is great because the player decides the level of play and level of time to invest.... not the game.

I would rather have the option, than not have it.

I plan on participating.

20 cities would be too much, besides reaching 10 cities is a hard goal to achieve. Also think of the time it would take to administrate 20 cities...
