I went through considerable effort to find a counter to thorn users... Ended up pulling the Vex/Mida out of my vault, it works very well, when used correctly... The rapid fire to the face technique throws their accuracy out the window... Letting me easily kill them with about 1/3 of the mag... Leaving me enough ammo to take out 2 more flankers, or anyone else grouped up with them... I still have to abandon double and triple team thorn fights, but that should be common sense... If your going to lose a fight, don't engage them...choose the fights you think you can win...and evade the rest... And do not assume because fusion rifles were re nerfed, that the Vex will not get the job done... The New legendaries from the Trials are quickly becoming a formidable force to not to be reckoned with...
