I can't decide for the pledge... Does anyone have any idea of the differences? I think I heard something along the lines of Immortal being unique, while the Everassur was not?

Yeah, that's right. You can take multiple Everassurs but only one Immortal.

Should be noted that the Immortal MUST be your Warlord. You can't take him as one of your Heroes. But the Everassur can fit into either, or both, of the slots.

So you could take an Immortal (Warlord) and two Everassurs (Heroes) or you could take three Everassurs (One as your Warlord, the other two as Heroes).

Just know that in my starter I'm going immortal cos I love the figure

Went for Megaman over the Everassur as well.

I got myself an Immortal and two of the Everassurs. Then again I spent an obscene amount of money on the KS so I may be in the minority here.

You won't be disappointed. You are gonna wreak havoc on the battlefield!!!

My starter was the Everasseur variety, but I ended up grabbing an Immortal as well (because when you are dropping nearly $600 on a game, why not!).

Both!!
Immortal and Everassur.
