I honestly wouldn't bother with BnS nowadays. While you can technically get max gear without paying, you are going to take years if you play casually, or months if you basically play this as a full time job (and then some).
Arena is dead and 6v6 is gear based. Your dps suffers so much from latency that it's not even funny. Certain classes are 'fine', but some can lose up to 70% of dps with bad latency.
