So, WD is not cross platform and probably never will be
how about this option?
When a certain player switches platforms (and we know it happens) he will have the option to request for a new account to be made that will mirror his current one, only on a platform of his choice. Once he switches over and logs in with his new acct on his new device for the first time, his old one will get disabled and kept in the records for future reference.
I believe the devs have the tools to be able to do something like this, and it would make a lot of existing players who have been stuck on a specific platform, happy
For example i would love to be able to play the game on my ipad (my phone is android)
