Loadouts are probably the best thing bungie has added to the game for a while, but even after I've used all 10 slots I still need more. There isn't even a 6th subclass out yet!
I know most who aren't as active/don't do as much endgame probably think "who the hell uses loadouts?" Or "who needs more than 5?" But most of my clan (ranked 9 to 11) have used 10 slots and still struggle with wanting to make more loadouts
I use all 10 of my loadouts Consistently depending on activity and have only ONE pvp loadout, I don't have a proper stasis build or more than one arc build , I really wish for More so I can experiment with more builds
