Forbes usually posts garbage, and this is no different.
Stopped reading after "you either have Thorn or you hate it". "You either have Gjallarhorn or you can't get a group"
I have every exotic out there and this guy sounds like an idiot. Thorn is stupidly OP and desperately needed a nerf. What's the point of the other 100+ guns if there's only 4 guns that matter in PVP?
Gjallarhorn is no different. It's the answer for [b][u]everything.[/u][/b]. What is the point of even having other exotics?
If you bothered to read more of the article it states balancing up other weapons to compete with them. It would provide more guns to choose from to be competitive rather than the 4 top tier weapons.
That just lowers the TTK in PvP and generally will lead to a less enjoying experience for everyone. I for one enjoy Destiny's moderate TTK. It's not too fast or too slow.
As for the G-horn, he's not wrong. I've kept it my heavy slot for everything since Week 2. There was no other weapon in PvE that could replace it for any situation... The only times it could be replaced is if there was any burn but Solar, and Solar appeared quite frequently.
