Neither does taking fire damage require Pyro, but Demon does require Pyro. And there are similar locks (kills +AP on Warfare or move -AP on scoundrel) which make less sense than these would.
It just helps out the chaff on stuff that is fairly useless to you, handy when going through that long list with quite little that actually is interesting (IMO). I see myself picking the same ones for all mages already for example.
And yes, that ping icon and chat do bother me. As stated, I keep confusing it with the combat log icon. I also need to check each time which of the 2 icons is teleporting and which is annoying sound, not used to that yet. As thus, it's "hurting" me.
Might aswell add my latest findings here, since they're few, and not worthy of their own post;
*Books burn in fire, huh? Nice touch. Although I lost the pokerplayers book in the ensuing fight.
*It would be nice if taking rewards I can pick crew members to compare with.
