problem, kalle, noone likes a lich, noone hangs out with a lich, a lich is not like a vampire-- you cant disguise it.
for that reason it doesnt matter if it clearly states its a permanent change becuase noone will want to talk to you in the game, and most will either try to kill you or just run away. so either this "fine option" turns into a straight path to world massacre, or a boring path to having rabbits as your best friends... and i would bet they would run from a lich as well.
aalllso, where are people getting the "stages to lichdom" there are no stages, its either your a lich or your not, you cant become MORE undead once your already there, all you can do is refine your powers (yeah, ive read alot and havent seen anything in canon, so if youve got a link, id be happy to read it), and after gaining the huge amount of power and knowlege to become a lich in the first place, thats kind of pointless.
if people want to use the canon to justify bieng a lich, too bad, the only reason any char int he game has become a lich is because they are evil and want to be immortal. so aside from immortality and the power gained from becoming a lich, its pointless-- it breaks the game, you cant join factions, you cant do the main story line, you cant trade, you cant talk to people (yes, even necromancers, and certainly the Mage's Guild would be very disinclined to speak to a lich). so its a bad idea.
-- but then again, dont mind my logic.. people in support will probably find some reason to vote for it anyway.
Eeeven if it was so, it could still be a option. Some people clearly want to be Liches, otherwise we wouldn't have them in Oblivion either.
Even if being a Lich meant that:
- Some guy tells you what the lich ritual is and what it requires, and clearly states that it's permanent change
- You get the required items and complete the ritual
- You become an immortal and magically very powerful Lich. Your skin is immediately replaced by the AI lich skin
- You live the rest of your life alone in some ancient ruins walking from one end of corridor to the another/ Rampaging around cities and nature
It would require next to none effort to do, and people atleast could be liches.
Also, if the people in game haven't discovered everything about liches, how the **** would we know? Corprus and vampirism were told to be death sentences in Morrowind.
Lich doesn't need merchants, not some citizens who can say 2 sentences about mudcrabs, not the guilds you don't believe in or completed months ago, maybe you saved the world (completed main quest) months ago too or you don't give a **** about saving it. The game is about freedom, you need no NPC, if you really try.
