I think it’s too make distinct that it’s not the first time they would be dealt damage, it’s the first time they actually take it. The wording’s too different, otherwise, I feel like. If they wanted Feedback Filter to prevent the effect, they’d have written it more similarly. Not that we can confirm for a few months, really, but I’d be surprised if things work otherwise.
But self-harming net damage stuff seems not unlikely, given what cybernetics do with meat and brain damage.
More on topic: I really love PE, but it does seem dead right now. RP does better overall and even IG seems to have more luck with the kill (even if Eater kinda screwed it over some I have hopes that Crick’ll help bring it back).
Maaaybe with Cortex Lock PE can ride again, but Cambridge style seems tricky if the opponent knows what to do, and the reason it became so popular was because of how effective it used to be. Playing around Feedback Filter was more than doable, but Eater + Keyhole is a nightmare for it. A more traditional corp build then just seems stronger out of RP, which makes things awkward for poor Black Tree.
Might see a resurgence when Chronos Protocol hits, many of the tools for CP will benefit PE, even if the attention CP is liable to draw will not.
