While I'm generally overjoyed that DH2 is back with the sane system I know and love, I'm not so keen on seeing the old psychic rules back.
Old beta's system had this nice element of wager to it, and prevented high-end psykers from effortlessly dominating without ever putting themselves at risk, which is all too easy with the OW rules. I also liked the fundamental logic of bigger effects being naturally harder to pull off, whereas in the OW system, it's effectively easier for a psyker to lift a boulder than a pebble, figuratively speaking. Separate Phenomena tables for different Disciplines were just icing on the cake, but a nice addition nevertheless.
I think the old beta's system could easily work with the generally lower values of the current system by switching the +10/-10 modifiers for every point of PR reduced/pushed to +5/-5. I feel this would make the psychic powers more engaging for players and bring back the feeling that each time you try using them, you're messing with powers beyond your ken, something that just isn't there if you can manifest at Fettered perfectly safe.
What are your thoughts on the matter?
