I say if you get the chance. Go to the exotic kiosk of lost lights in the tower. And look at the required materials for the Le Monarque exotic bow. And aim to get that bows whenever you have the chance to. It’s a wonderful bow to have for both PvE and PvP. And it is great for end game content like GMs for playing back and safe. The catalyst is very handy too as it comes with the unrelenting perk which gives you healing on multiple kills or kills from stronger combatants/targets. I definitely recommend it. As for legendary bows, check out banshee(gunsmith), as he usually sells some decent ones with pretty good perks.
