I'm sure this has already been addressed but after starting my Hunter the last 2 days and playing with the Gunslinger, I have come to realize that the solar subclass is virtuously useless in D2. I thought my main character's (Warlock) solar subclass was weak (same with Flaming Hammers)...until I played with the Hunter. I ran 2 strikes as per the Milestone and the challenges were based around the solar subclass, it was almost laughable how useless the golden gun is. You use your whole super on a elite enemy and it might take his health down 1/2. Very frustrating. The grenades were like throwing rolled up toilet paper that was lit with a match. It did about the same damage.
Off topic but received the "solar" skyburners oath and used it about half the strike and it was repurposed to the Tone Patrol. Completely useless (IMO.)
I dunno if I'm the only one out there experiencing this or if this is a topic that is being discussed.
