Well we already know we can't be necromancers (No necromancy school - and for it to be effective it would need to be its own skill), but I would like to see some mysteriousness, yes.
actually, there is necromancy, it governs mysticism and since mysticism, has been merged into other schools, it will likely fall under conjuration, and you cant say theres no necromancy, bethesda HAS to include it this time, every single person to have played the series and on the forums almost has demanded necromancy, if bethesda wants to destroy what the people want then there destroying this game by not giving us what we want, if i find out that there is no necromancy i will not buy this game, im tired of seeing and being around all this amazing stuff in front of me in the game powerless to join in on the festivities, it would be BETHESDAS BIGGEST MISTAKE to not add necromany into the game hands down
EDIT: i mean oblivion they had only 1 evil faction the dark brotherhood and like 5 good factions? WTF THERE SHOULD BE CHOICES IF I WANT TO BE A HOLY KNIGHT (WHICH DOES NOT APPEAL TO ME WHATSOEVER) whoops caps, i should be one and if i want to join a daedric cult or necromancer cult that should be my right playing the good guy is stupid so many people wawnt to do other things like raise undead armies and all kinds of things so i pray that my all time game company makes the right choice this time, i love bethesda and just know they have to make the right choice this time. were all counting on them to make are roleplaying experience wonderful and rich this year
