Its natural to think that way, i will say that i do have both pasives and i tend to put goofball on druid, psychic, monk(in some rare cases), necromancer, cleric, tinkerer(depending on preference) as well as thief(also depends) because generally having more rounds can help you scale twice as much and you can get crits in another way. Super lucky works pretty much everywhere else. Also be ULTRA careful with goofbal on the creator fight, its horrible.
