@MichaelIgnotus:
I answered to the post from @noStas and not to yours. I messed it up a bit by not answering direct to his post.
I really like your mentions in your OP and only get a bit deeper and more restrictive in my thoughts.
Ahh, ok, I missed that and with this my example would be very rare.
But another one:
Sitting with one assault save behind a wall (out of LOS, 1 tile away to don’t get hit by enemy) for peek-a-boo. In this case i could step out, do 2 shots and step back to a safe place.
Then you have to “shift” an ability to a target. I don’t know if that will work, but maybe. So why not, sounds not to bad.
