I believe there is a risk of a civil war for the Forsaken. My speculation starts with this: Sylvanas is a hypocrite. The main grudge, the entire drive behind the Forsaken is that Arthas had raised them unjustly from the dead. No Forsaken wanted to be raised as an unholy soldier. Sylvanas loathes being a banshee and hated Arthas for making her what she is. Now, to strengthen her military might, Sylvanas is raising her own undead. Undead unwillingly resurrected. Undead that are given their freewill, but undead nonetheless. Undead who could(potentially) hold Sylvanas accountable for her actions. I doubt any newly risen Forsaken would rise from his grave to be greeted by Val'kyr and the gravediggers and fall to his knees, swearing servitude. What I see at most is an official lore explanation for this, what I see at least are RP undead rebel guilds in contrast to the Sylvanas fanatic ones I've seen since vanilla.
Thoughts? Rebuttals?
