I've encountered him 3 times (once on the Warsat event, and twice with the invading armies event).
On all 3 occasions there have been 4 or more guardians and we've barely been able to scratch him. What gives?
Any tips on how to take him down? Reminds me of Randall the Vandall on steroids.

I've done it twice, you usually need at least 3 other people. The hardest part is getting his shield down and constantly laying on him since he spawns near the end of the Public event so all the other enemies are going to be really strong. Once his shield is down, hit him with rockets and supers.
