What if...instead of choosing which psychic powers your librarian, sorcerer, hive tyrant etc. had it was randomized, like (current) WHFB spells?
We already have examples in current rules, like the Inquisition Adversaries and random (per turn!) Weirdboy powers. But what if every psyker had to participate to some degree? No automatically getting Lash or JotWW? The Horror!
To make it work, we'd need a bunch more powers available for the most part. Some books already have a number of powers available, but you'd need to flesh out those possible for guys like IG Primaris Psykers.
What do you think? Should the psyker world be shaken up and force players on both sides to adjust a little more? Or are you horrified at the thought of not being able to buy a particular power your whole game plan centers on?
Which reminds me...for the next doubles tournament I go to I have to remember to make that double-lash, quad-JotWW team-up...
