I agree it's just a game and it should be fun, but sadly for a growing number of players it's not. And this I think bubbles down to what you said about thorn being a challenge to overcome in crucible through skill. However it doesn't really matter how skilled you are if it's not one person using thorn but two or even three people on the same team all using it. And that's what has everyone so upset, it's not the OPness of the weapon, it's that everyone has discovered how effective it really is and are subsequently using it as their weapon of choice. This was because of its superior range and DoT, it didn't matter if there was damage drop off for the round fired, the DoT made certain that you needed at least three successful shots to kill anyone at any distance. I agree nothing is infallible but You can't deny that there is strength in numbers, one last word can't beat three thorns. It's not fun to consistently fight against people using the same weapon as everyone else. I think the nerf was deserved and if others really think that it will ruin their play style well there are other guns to use. I however (if I ever decide to start playing again) will stay with my last word and adapt to the situation just as I always have.
