Ludia: Please Fix This

I love JWA and I’m not just here to complain about the problems that’s are in JWA but here are a few that really bother me and I just want them to be made aware.
•Friendly Battles- Every-time I request one my friends say they never receive an invite and when they send me one it always creates an error that makes me wait a minute.
•Campaign Stars- Some of the challenges to get one of the 2 stars in campaign are almost impossible for a player to do and needs fixed
•Achievements- Some achievements are fun and others are nearly impossible to do. Just some of them need fixed. Also please remove mystery achievements.
•Also I love Rexy but I think we all want to see Spino a legandary non hybrid like Rexy!!! He’s a fan favorite I’m sure most players would love to see!!
