About the tier list

(first sorry for my english, I am a french DBL player)

To start, thank you for your work on your site, it is perfect

I am active moderator on a facebook group on Dragon ball legends and many questions often come back on the officiality of a tier list of Sparking, so I would like to know in order to answer to the questions of members.

why do you say "official"?

do you have links with the developers of the game?

Give me the maximum information on the creation of your tier list please

Thank you for your reply
