ahem, quite a lot is supposed to be new.
for one thing, the fact that they're making ladder chars kind of like hardcore, they have their own games and crap, and you can't convert an earlier char to a ladder char....also, they're doing the usual, tweaking skills like hydra.....and i think they're making it so you can't have pierce and guided at the same time, so the arrow can only hit one thing, not multiple beings.....
