Do the hybrid classes still count for fulfilling the prerequisites for feats, or class abilities?
One example would be spell mastery (feat) where you have to be a first level wizard to take it. Does Arcanist fulfil this prereq?
Also If I were to go Bloodrager and Barbarian could I use my bloodrager levels when considering that Rage powers I could use?
For example as a 4th level barbarian with 2 levels bloodrager, could I take a rage power that requires me to be 6th level barbarian?
