Has anyone done BLU yet for 6.45? How is it?

I do plan on leveling BLU up to 80 but I hate Mask Carnivale with a passion, it is boring to me & have not done the Siegfried fight & really don't have any desire to do so which is sad because that is the only way to advance in BLU's storyline. Which I always thought was a bad idea tying the Mask Carnivale to BLU's storyline. I know I'm missing spells from totems you get from completing a certain amount of levels. My Blu has i400 augmented gear but only the i130 wand...lol.
