What rank do think is the "not being a Noob Rank" anymore

Anywhere from Silever 1 to Gold Nova 3 I'd classify as 'being a noob/somewhat of a noob' as most accounts I've played on I've gotten gold nova 3 most of the time (although I had been playing MG2+ for a lot of those accounts). So I'd say anywhere from Gold Nova Master and above isn't 'being a noob' anymore.
