I got my Hallowed Eddie from a G/A soul - not an event soul.
But several of my Troopers have him so he IS dropping.
These rare toons can be tough. It took some like Carlos, Kamuz, and GMAC - guys who play more than most and get lots of G/A souls from outstanding PvP performance - a year until the Gimp dropped.
Toons will ultimately find you. But it can take a long, long time. Expectations rise during these events because they say “increased chance” - but they’re still 5* toons and not easy to get.
