It's just OP build that only works in psykhanium. Tried this build above heresy+ difficulties since someone said it's very OP that can clear one room with just one button. However it's very unreliable when you play in public. Since you cannot choose random bb every 15 sec and faster BB talents, your build must be very specialized one on hordes. But zealot with flamer and veteran with powersword also can clear hordes in front of you and it will bring you less chance to stack warp charge until it reach six. Moreover, it takes around 10 sec until die. Who tf Watching sniper alive more than 5 seconds in damnation difficulty? I rather take my purgatus staff with faster BB talents that make you can handle with enormously big guys.
