Hi Lushi,
My recommendation: BlackoutRO. It is a highly customized Super High Rate with a focus on Battlegrounds, PvP and WoE. There is beginner gear to get you off your feet in reasonable time. It is one of those servers which is spam-heavy, which sounds like it could cater to your needs.
Here is a small PvP sample from June last year.
