Sigh . some Defender Companions are amazing even for DPS . I can take my DPS HR into CN , with a Helmite Paladin Ghost Companion . I will then proceed to Tank , Heal and DPS all at the same time , in fact the other 4 players are usually just there to tag along with me . With my Pally Companion we do not need a DC to heal anyone , we also do not really need a Tank either . Also the Frost Mimic is class as a Companion , makes himself completely immune for a lot of the time in combat . As does the Helmite Paladin Ghost , he seems to be completely immune to a whole load of attacks in the game . I can pretty much carry ANY 4 players through any of the content except FBI as I am still in the process of unlocking it . Please go and fully test out 50 or more Companions and then come back with your opinion that DPS should not be using Defender Companions . Also some Defender Companions do not actually generate threat .
