:D Becasue Mesa 4th ability has absolutey nothing to do with any other frame ability. Even Saryn spore can go trough it !! Isnt that same?! NO! Mesa was ALWAYS !!!! Able to do that ! Since here release. If you dont know that I dont know what to tell you. If you are just talking only to tell me how OP she is pls dont! If you are going to help then stick around :) I'll be thankfull!
But realllllly if you dont know what she was able to do before the update and it was never considered as bug please find another topic. Plenty of them around. I am annoyed enough about that thing not getting fixed for for I dont know how long. And btw this happens every single time with Mesa with big update!
