So I went to do a solo run for Prophesy due to a patch that fixes very frequent Psion splitting. Now before Taken Psion splitting was happening when the Dungeon was re-released in Beyond Light which made it super difficult for solo runs, making me not want to bother doing solo runs. The 1st encounter is shown that the patch was in place, the Psions weren't splitting that often and the AI seemed dumb down than usual, if not then I'm just out maneuvering them. Throughout the Dungeon seemed to be in a normal pace, no Psions were seen anywhere before the last encounter. Until I made it to last encounter.... I don't know why but Psions were constantly splitting whenever I attacked them, I was getting overwhelmed by the amount of Psions with the stacking of the Knights and the Boss. I thought this was not going to get this frequent, did you forget that Psions have a presence in the last encounter Bungie? This was the reason why I stopped going to this Dungeon, I can't solo this, It's already a tough encounter and the Taken Psions makes it brutal with this behavior. So Bungie you either forgot or got lazy on the patch notes that you fixed this. So please look back on this and fix it!
