My biggest beef is low hull ships become extremely vulnerable to this. Anything with a hull value of 2 or below this is a major threat to, and really, anything with that hull value is not the hottest ship ever outside of the imperial lists. Many of those ships are already hurting for help anyways, and now they have it even worse off in the game. I am talking about things like the A-Wing (which is just about where they should stand in the Meta currently), the E-Wing, and the Scyk. It is a serious and unnecessary blow to these ships.
They are only vulnerable if they stress themselves. Just don't PTL. Find another EPT than the most over-used card in the history of X-wing.
If they stress themselves to use PTL to take an action that will prevent a point (or more) of damage then it's worth running the risk that slicer tools might damage them the following round.
