My main has turned to the Dark Side and is now known as Darth Mologolom, so obviously will be a dark Necromancer. Except he can't because Zos don't sell class change tokens.
My guess is thats to do with what skill a char has. Well a class change token might work if it took away any skill points associated with your old class and make it like you never were that class. Then you just learn Necromancy skills from scratch like everyone else, except you already fully levelled in everything else. So the chanmge not a big deal.

Please, please Zos give us class change tokens, allow Darth Mologolom to further study the Dark Side of Nirn.

I definitely will create a necromancer and have fun trying out the skill line, but I probably wont grind them up to level 50. They will ultimately be a daily writs crafter with neutral necro tendencies. Back story will be they dabbled in necromancy to help speed up their crafting work since so many of the mats ingame are dead animal or people parts. Just animate some of the mats to do some of the crafting work!

To heck with being stuck in one of three boxes. I’m going Purple, cuz nobody puts Necro Baby in a corner!

I will play a gatekeeper.
Those whose time is not yet to come shall be protected from ever sleep and prevented from walking through the gate.
Yet, those that chose to runway from my protection might slip trough to oblivion and, well, it would be shame to waste that corpse of yours.

Considering time and effort I have to put with each new character (shards,mage guild, fighters guild, undaunted, pvp rank for simple skills like purge or barrier or vigor)... I am 2 lazy/got not enough time to start everything again from scratch.
