If SE catered to raiders, the jobs wouldn't be this braindead. I'm a bad player myself, but everyone can read a guide and join a discord without actively sabotaging players.

Also, I figured out how to upvote on mobile.

Since ciphers get refunded if you leave instance, if this sniping behavior continues and people like OP keep ignoring the polite pointers in /say, people will just straight up start leaving instance immediately when they see unresponsive or intentionally sniping players, or have everyone bring 3 ciphers minimum.
