I keep seeing people talk about how Biggs is going to be unkillable because the Rebels have gained this godlike new EPT. Just put Selflessness on a ship with Regen, and Biggs will live FOREVER! However, that's not how Selflessness works. As the card states, you must discard Selflessness to suffer the damage from that attack. In addition, it's dotted, so you can only have one copy in your entire squad. As Rebels currently do not have a way to restore discarded upgrades, that means that Selflessness is a trick you can pull exactly once.
You may be able to soak a would-be killshot, but that's all this card does. You're not going to be relying on it every round. In most cases, it'll mean Biggs requires one more attack to kill than he normally would have. That's still really good, especially for one point, but I feel like there's a minority of players who are freaking out because they simply didn't read the card.
