Ah, the nerf turn 29 and 30 person is back at it, i see you managed to beat those ? Congratz!

"needed BLU spells." -> for what content exactly? Bluemage Raids for Morbol or the new savage ones?
Bluemage is a optional character for fully optional content, mostly endgame / speedrun / solo related - which mostly is a challenge in itself. Doing the carnival stages is fair, the fights are not that long and every time you fail you learn something new about the fight and improve, just as you finally did for stage 29. If that doesnt give any feel of accomplishment to you maybe you shoul'nt do this content because obviously its not fun for you to do so, but for the love of god let us have some challanges besides multiple person trials. Carnival is fun as is and everyone can beat it if you learn the patterns.
