If they are using multiple accounts in the same world then they are already cheating the system
Not true. Official answer from the support page:
Can I play more than one account on the same world?
Yes, in Elvenar you can play using as many accounts as you like, even if that is on the same world. Please do note that if you choose to play using multiple accounts, all of our
game rules apply to each of the accounts, without exceptions.
Example: Even though playing with multiple accounts is allowed, it remains forbidden to create or use one or more account(s) as a "push-account" to benefit one or more other account(s).
When we send an idea to the devs from the forum, they take us much more seriously if we address their need to design features that do not entice push accounts by providing overpowered rewards for doing so. There is already an issue with push accounts using kp to advance AW's. It takes very little 'normal' playing of a city to circumvent the policy accurately stated by
@BQwer
As part of the requirements the devs have (found
here) for our volunteer mods to even forward an idea to them the downsides to the idea need to be addressed. Failing to follow the requirements they've set for looking at ideas means we're just talking among ourselves here...again...
