Well...Is it worth? Yes. Should you try to get one without buying it? Definitely. But if you want to do endgame content and don't have a legendary primary then go for it. You need legendary weapons to get through the hardest parts of the raid, for sure, unless you are very skilled. The raid usually gives tons of Ascendant Materials, so you don't need to worry as much about those the further your progress. Edit: Auto Rifles and Scout Rifles are the only weapons worth using in the raid. Handcannons don't have sustained damage, and takes to long to kill because you won't always be able to get the precision shots, and they are useless against the bosses. Pulse Rifles are..meh. Small clips, not much reserve ammo, unreliable damage because you can miss shots etc etc.
