So I'm relatively new to DH, didn't play 1st edition, and I was wondering if anyone else thought it was strange that one of the aptitudes needed to increase willpower cheaply is Psyker. Why not defence or toughness? I feel like willpower is an important skill for every class and to relegate the ability to purchase it cheap to one doesn't make much sense to me. Especially when you look at the Untouchable elite advance. You have to get an insanely high willpower to purchase most of the talents, yet it wouldn't make much sense for you to build an untouchable character with the psyker aptitude.
thoughts? Is this a balancing mechanism to make sure psykers don't become irrelevant due to more characters being able to pump up insanely high wp?
