That was the post I made about a zerger who complained that I didn't heal him. So, I squelched him.
After a few more levels (and weeks), I met him again while gathering discs in IQ (Inspired Quarter) to farm stuff in Mindsunder. Since it would be troublesome to not be able to see his typing, I decided to remove him from my squelch list. The end result?
3 runs of Mindsunder later, and he lets me loot his Elocator's Habiliment, Dream Edge, Gloves of Titan Grip and Regalia of the Phoenix.
The point is, I was so close to quitting the party in the beginning when he joined because I still remembered the reason for squelching him but I didn't quit because I believed in giving people a second chance. Apparently I was rewarded for it. So next time, give that squelched fool a second chance, something good may happen to you.
P.S. If there is someone who you KNOW deserves to be squelched and you don't EVER want to give them a second chance, then just ignore this post.
