The one big reason why MP was removed and the hacking problem left undealt with was because of development of SF: DG2. I believe it is to be expected in spring. If I am wrong about that, please correct me.
Actually, before that, Fission Mailed was used in Metal Gear Solid 2: Sons of Liberty, during the fight in Arsenal Gear right after Snake gave Raiden the HF Blade. The screen changed into the game over screen, but said "Fission Mailed", but you still played the game.
Another one of my ideas while showering:
A spell that decimates a square are (5x5, 6x6, whatever). The spell doesn't allow chains, and doesn't activate the abilities of any powerups in the radius.
