I'm pretty sure the -special is the highlight of the focus interaction, as I've said to you many times now, the stuns aren't as important.
If I can permastun a +4 AV without it's triangles up as a stalker, I really don't see the complaint here.
Like, I get it - cottage rule, I don't like core abilities being changed much either, but there's a tiny detail you seem to be missing here.
STUN WAS A GARBAGE POWER.
