Whats the all time active twinks pvp level?

[Hail]

46 for sure, most active generally, though during PVE events it's less so usually, plus you can do all of the "elite" level timed runs.

Gotta love them elites.
OP try 14-18, I recently joined the 18 zone and suprisingly many guilds fight fairly, with the exception of two. It is active, enjoyable and darn right a good level to pvp.
