Rush doesn’t need nowarning as it’s impossible to rush yourself because you don’t meet the minimum distance.
Rush doesn’t need nolock as it's no longer free-targeted but can only target creatures.

If the automatically calculated target *is* the player, the ability is almost certain to be a heal, buff, or other thing that makes sense to apply to an ally, and the autotargeting should proceed.
If the automatically calculated target *is not* the player, no self-target warning would trigger anyway, and the autotargeting should proceed.
