Use this forum for random changes that would make the game slightly better. I'll start.
- All Adept Weapon mods now drop from all higher level content sources (GM's/Trials/Master Raids) [Not exclusive to any specific gamemode. Looking at you Adept Drawtime]
-
A quick Google search would have told you all adept modes drop in GM, master raids and flawless trials except adept icarus which is strictly trials.
