There’s some really interesting changes coming for 2e! Bards have full martial proficiency, clerics can f finally get heavy armor from within their class, wizard schools of magic are gone… Then of course the big named news, like the replacement of dragons with the magic traditions (arcane/nature/religion/occult), and the completed removal of alignment.
Are other people as excited as I am?
The planes are sticking around, actually. Just character alignment is going away. :)
