this is like the post I would expect by someone who started playing the game a week ago! I mean... what.
Conventional wisdom was that Thorn used to suck. It didn't, but it was a finesse weapon that you had to build around. Yet I read pages and pages and pages about how it was shit, embarrassing, a worthless Exotic bounty, the #1 gun needing a buff and so on and so on and because of all the people crying it is now in the state it's in today, where it simply outclasses even the weapons that are closest to it in pure statistical reality- along with having a unique perk with advantages unavailable on those weapons anyway.
Should not the people who thought it sucked simply have figured out how to overcome the problem, rather than wanting to have it changed for them? If not, how is your view here even remotely consistent?
You can say "there will always be a weapon used by everyone" as though a "Thorn-like situation" is an unavoidable reality but I honestly don't have a clue what it is you are implying fit in that slot during the balance phase following the initial AR nerf but prior to the Thorn buff.
