i hope they will add more for the ranger, we have the gloom stalker, (perfect for the underdark) the horizon walker and fey wanderer.
And where are the divine powers and psi powers ??? there is the psi kinght that can be added (when using the tadpole we get access to this class). there is tons of subclasses , some in UA would fit perfectly for the game (with psi powers) i know they won't add some like (the samurai, it would be weird unless we are a far stranger new to faerun, because we got abducted , somewhere, we don't know...)
sorcerer have tons of subclasses too, i hope if they don't put everything in the full versions, they will add an expansion or DLC for more subclasses, allowing more replayability.
Moreover, we can say they got very well funded for the EA, so the only excuse they have now is the time, but i am ready to bet that players are ready to wait for more contents (the lvl max will be between 10 and 12,
).
