We kill it between the fourth / fifth burst "usually". Note that burst happens every 25 seconds, which means that to kill it before the fourth burst (~90 seconds), you need to do 70K dps amongst you, with zero healing on the boss. It's fully doable, to be sure, but experience tells me that you'll probably have the boss healing for (on average) 2 ticks per beam wave, adding about 12% health to the fight (or 8k dps) - one time might be one completly fucked up, another might be perfect.
Either way, you need 3x dps doing 20K each and a tank at 10K (or tank and dps all at 17.5k) with zero fuckups to do it before fourth burst.
