then you do not need any build guide or so, just take Inquisitor and a mastery with default attack replacer: Demo,Solider, Oathkeeper or Shaman (which you did not wanted to use) 
Demo: Fire Strike - has explosive strike and fragments from the last modifier: together with all the default attack “proc” skills (WPS) from Inquisitor you can get nice AoE
Solider: Cadence - massive Weapon damage and buff from Deadly momentum. The first modifier Fightning form make the bullets pierce through monsters! Also has a transmuter for elemental damage focus.
Oathkeeper: Righteous fervor - has chargers that will multiply the damage of the WPS that procs from it. Also has a nice speed and tank boost on the first modifier.
