Definitely agree. I get exciting new skills.... aaaaaand then can't use them in the dungeon.

And then when I do get into an a-level dungeon, I forget the skill is even there because of the numerous roulettes I just did without it.

I adapt. It isn't something that will ever make me quit, but I agree it would be nice to be able to use my full rotation in every piece of content, even if the potency had to be severely limited.
