Well, anyone who has been following the meta knows that jedi teams are out and healers are on their way out. You're new, so I'll give you a quick on the meta shifts.
Healers were it. Every team had a minimum of 3. The healers synergised well with jedi, and then the meta started shifting towards jedi. After the anti jedi patch, the meta shifted away from jedi.
With that said, sid is a counter to healer heavy and jedi heavy metas. He wont do porely as he is a strong hero with a nice kit, but with the meta shifts, sid is fast becoming obsolete.
I would strongly suggest that you stay with what you are doing, and don't follow the FotM. Your path to droids will put you ahead of the meta by the time you level up.
