The praetorians weren't as hard to kill before the patch when I did the raid, now as a lvl 30 none of my exotics do enough damage after I've taken their shields down, and their spawning pattern changed, my last word is 3 upgrades away from being maxed out, not even taking [ ] worth of hp off praetorians, my rocket launcher is the only gun that even fazes them and its maxed to 331. did they get a buff in the patch? it sure feels like it. Exotics: Thorn, Last Word, Ice Breaker, Bad Juju. all have been leveled up at least once or twice.
