I've farmed 10+ Prowling Chest and have yet to land one Treasure Key. Is this usual for anyone else? Since the update that patched the prowling chest, I've only landed around 3. The only other ones I get are from Petra once a week & on occasion running the PoE and opening the small chest. There needs to be a dramatic increase in drop rate (33%-45% at least). My suggestion would be to include an alternative, trade Variks 3 Tokens of each kind for one treasure key. What do you guys think? Any suggestions to fix this issue...
