Meggena81, it really comes down to whether or not you're willing to look at other areas to obtain weapons. Right now, at time of writing (pre-1.1.1 patch), Thorn remains an excellent PvE and PvP weapon, but is it really worth an exotic slot? In PvP, yes. The Damage over time and the fact that it's AT MOST a 3-shot fire and forget weapon means that it's earned itself quite a reputation. Is it the best exotic handcannon though? I don't think so, as both the Hawkmoon AND Last Word have the potential to kiss in faster times in PvP. In PvE however, I'm not too fussed. The impact is decent, the rate of fire is average and the damage over time isn't really that noticeable, or useful as you'll rare be relying on the poison to kill your enemies. There are several Legendary weapons that can deal the same damage per shot as Thorn (TFWPKY 1969 and Word of Crota come to mind), and also if you have Timur's Lash on hand, that handcannon deals the most damage per shot out of anything else. Sp ultimately, if you're willing to put the time into obtaining Thorn it's well worth it, but if you just want a really nice handcannon, it's also possible to look at some legendary handcannon and save your exotic slot for something else *cough* Haterhorn *cough* Hope this helps out! - Sasssi
