actually I think the opposite would fit far better - the PP are a great thing to stop grinders in their "tracks" - this is an RP, so...
what I would like to drop is the sometimes outright insane pricing for training, as in comparison too few tria get "dropped/looted/earned in quests... so either lower training prices, or raise "income"...
the theory/practice system is something that IMHO makes PS stand out; one could, if at all, maximally argue which skills are theory/practice to which part, but most I see so far seem to be classified "correctly" here.
