Personally, i feel Nokris was a lot more of a decent fight than Xol. Xol should have had a grander scale of ability rather than 3 movesets; beam, blast, wriggle. The adds weren't challenging too. just kite, and headshot. No biggie. The heroic version was slightly better; the fight felt more pulse pounding, the damage to a GOD was more in line with expectation. but overall, just felt sort of disappointing? the payoff wasn't him swearing vengeance upon us, or calling the hive only to be disintegrated by a Valkyrie blast from Rasputin itself.
