I'd rather ban Argitoth from here
But to be on topic - I would be happy with removing all assassinations from the game. It is really just annoyance with current game mechanics. That is random and really luck dependant. And it brings a huge load of frustration sometimes , when a commander with retreat order gets attacked that way or some communion master with strange script. And manifestation is one really ugly assasination spell. I have been attacked by it several times.
