Attacked hero that switches personas

Although it doesn't create huge flaws in the game, when switching heroes upon being attacked, creeps or heroes sometimes follow the moved hero to the place you hold swap personas. Maybe hiding the unit can prevent that or adding a taunt/trigger that retargets the people attacking the old hero to the new hero.

there is already a retargeting system which does properly re-direct player controlled heroes if they were attacking you.

we could care less about units -- tracking that is too expensive to matter
