Ah, right. the tedious (Endorse/protect, let the rest) and so on. Just a personal thing, but I gotta admit I'm not a fan of them. They interrupt my exp skip spam, but while I find them tedious, I have to admit the free bonuses they provide do alleviate any irritation I may have had initially when they were first introduced. So silver lining and all that.
