The mida and vision are most definitely not counters for the thorn. Thorn has a quicker ttk than both and about as much range, not to mention better aim assist. I could see you maybe out gunning someone using a thorn with the mida if you were running dance machines, but that build requires a hunter only exotic and requires perfect headshots, while the thorn user only has to tag you 3 times and run. No, dont wanna hear how you do it all the time. Thats great, but all that means is you have better gun play skill than the average thorn user. I'm talking straights stats.
