Interesting idea but it wouldn't be hard to set up rexlar with Ptl, an hlc with jendon beside him.
Consistent 4-dice Tl+focus plus an extra focus token to flip crits.
This would be game breaking, he'd destroy anything.
Plus, vessery's whole game is setting up for Tl+focus shots anyway,what's he going to do if his action is freed up from the auto focus and he doesn't need to Tl because of his ability? Basically, this gives vessery the situational option for w free boost
While it makes brath a total howitzer.
The defender needs a fix and focus does seem crucial to the defender so I get where you're coming from, but this doesn't seem to quite pull it off.
