I'm in the process of creating a spreadsheet that will suggest optimal teams based on selected leader and game mode (ie. Arena, Raid [and phase], Events, etc.). I'm looking for as many people to mess around with it and suggest changes or improvements, so don't hold back your comments.
If this looks even remotely interesting or useful (even if only to beginners), please give me an upvote so that more people can be exposed and have a look.
Thank you very much for your interest and support!
