Yeah I disagree with that, I haven't played dust palace after the nerf due to being on xb1 nowadays but I run that pretty much every 3rd strike on my ps3 roc playlist and it's ridiculously simple. 3 guardians focus on one psion at a time, use weapons according to their OBVIOUS shield types and avoid the centurions/collosus' that spawn, hell you can make it easier by FoH-ing the far left psion off the map as soon as he spawns! The ta'alus nerf is unnecessary too, I solo'ed him on a roc strike yesterday (2 others departed, might have been lag) and there was no feeling of challenge there at all. Damn nerf wailers.
