I agree completely with this post (BTW, I don't have a Thorn). If you see your screen turn green or you hear the trademark sound of the gun it's time to adopt your strategy. I know the HC have a great range, but not that many players are good at long range sniping with it. I usually use the Vex at midrange and that's very effective against most Thorn wielders (most can't focus while barraged with a Vex salvo) TL;DR: adopt your strategy against enemies and their weapons.
