Nearly every single fight that you show in the video you have a trinket used, pvp buff, and a pvp potion on. 5% from gear 15% from pvp buff box 15% from pvp stim extra power from trinket ect In nearly every snipit you've shown us you have +35% pvp damage bonus activated. Nothing but a look I can make numbers with lots of buffs activated. I have a 50 IA and yeah I can do what your showing too it's not difficult. But it's also rather easy to counter an agent if the other side plays correctly or just rolls a stealth class.
