My list would be topped by people in Ventrue. Back in 2010/11 when i was fairly new to the game i was in Ventrue and the people in the guild such as Gambit,Death,Angelus and Selena Coterie were all quite good, Ventrue was never really known for there sparing but overall they were one of the top guilds due to loyalty and skill throughout all of the members--Aserus in my opinion is the currect top active underrated sparer--
