Street Brawl - What Level does it start?

[murf]

I'm L8, and if it's starts at L10, I'll level up to participate in the first few awards.

Does anyone know if it starts at L10?

My L21 has it... well, now L22 because how can I pass up that explosive! LOL

Leveled up and it started at 10.

Yea, was going to tell you it probably starts at 10 because my level 11 has it.
