I agree. Jellal told Erza to lead the way to the light, so her becoming a Wizard Saint and joining the Council would be the most appropriate path for her character.

As for Wendy, I just said some comments ago that I also want most of the FT members to turn Natsu and Lucy down, and later all of them come together at the same time to help them/join them/whatever. Idk it just seems more realistic this way.
