that does make sense. Possibly Tyrael defeats Imperius and then stabs the spear into the ground and starts to walk away and imperius takes advantage and casts him out of heaven while his back is turned. thereby Valor turning to wrath in that attacking Tyrael with his back turned isn't very valorous.....

The comic factors into the game. I think jacob might even be in the game. The only issue i have with tyreal taking solaron is that its supposed to be a part of imperius. The literal physical manifestation of his will.
