The multi-accounting was introduced during the 1st server merge in like 2015 if my memory is correct, so we've had a decade of multis and they will never go away. It used to be simple and fair to have only 1 account per server from 2008 to 2015, but sadly our player base slowly declined over the years, which is why server merge was a solution to populate those dead servers. As a result, the rule of 1 account per server was removed and multis were introduced. Suddenly everything feels unfair when multis work with each other, forcing old veterans to make more accounts to get an advantage. Hopefully that answers your questions.
Personally it's enough with 1 account, it's too much work with 11 accounts for just a game. At least World of Warcraft had variety for what type of character you wanted to play while another Ikariam account had no variety at all. You know what they say, no one is perfect, even games. As someone who played both games casually for nearly two decades and managed to quit recently, it comes a time when you have enough and move on to other games. That time usually comes during big updates that make games less fun to play, but you can't expect the developers to revert those changes.
