It does not really matter whether you are optimistic or pessimistic. You filed your application with an ineligible sponsor (an outland PR). You can either wait and hope for the best and potentially waste more time on waiting (if finally rejected) or you can withdraw your application and apply again (and control the damage for 3 months waiting).I'm already not a very optimistic person, you both seem to be the same..
Anyhow I can't argue with professionals like you, so I'm giving a last shot through webform and email to Rome VO and then we'll withdraw if we got no updates..
It is your decision.No one can guarantee the result if you keep waiting with your current application though we all will cross fingers for you if you decide to keep waiting.
