While BBW was a pain, Gonzo was just as horrible. Now I think Edna Mode and Figment are going to take the place of worse characters to level up. At least with Edna, more than a single character can collect the different tokens. BUT, the characters are tied up for a long time and you have to have HUGE attractions out occupying space.
Who knows how bad Gantu will be or even the Dormouse (once I get to Level 150).
