There is one big thing about multis use in regional server:
It directly effects artifacts and regional control and server winning and loosing if they put multis in alliance
You don't know what I mean cause you didn't see what I saw. Making alliances of multis just to settle second villages in one region and bot them up to 250 pop to deny the effect and vp is a real thing.
And no - this last ptp server I played was just worst than any ww server I played in past 12 years regarding multis and script use.
edit: actually you can see it I just posted an image of it in last page. Imagine 3 fake alliances like that.
