Nah, this has nothing to do with your role. That was me saying you're a crap player, so if you got Mislynched it would not be as bad as if a good player (say Drago if he was in the game) got Mislynched. Your role had nothing to do with the assessment, as the assessment was about the worst case scenario in which you were Mislynched as Town and how big a setback it would be.
That said, I thought Don DaSlayer was a crap player and he won last Mafia game, so I can't say I'm very confident in my reads of good and bad players. Anyway, I wasn't advocating for your Lynch, I was giving my take on the plausible reasons Celestia decided to Lynch you.
@Jew D. Boy asked, and I answered his question because I wanted him to have a better Mafia experience this time around.
