I agree with the idea of bringing back locked drops in KM3. Right now the most efficient way to farm is by using gold loot ,which cost gold, sometimes a lot, to even acquire a decent amount of gold from Elite SG/Maus. You may say another way to farm is Forgotten Ruins, ruins is easy to farm ,and unneeded of gold loot, but takes too much time to acquire frags to get runes. Platinum runs in ruins can acquire a lot of gold but there is only so much plat you can acquire from offers, unless you want to spend IRL currency for plat. Please bring back KM3.
