Why add key uses to normal keys when 90% of the time loot behind locked doors suck. Look at ultra med, loot behind that door has been run into the ground. Run all the way across the map hit power just to run back and open the door to find maybe 2 army bandages and a CMS kit.
Shoreline suffers from the same issue. SanScamitar office key used to be one of the best keys to find a LedX and after going through almost 2 keys (nearly 80 uses) I haven't found one! Combine that with wasting a key use 1/15 raids due to someone vacuuming loot from outside a locked room and the situation gets worse on shoreline.
Dorms went from being one of the best PVP spots in the game because marked room used to spawn good shit now it's a ghost town 80% of the time. I miss the days of finding a SICC case inside of dorms and having to fight my way out or running away while a dude with an altyn chased me down.
I dunno man but the current system in the game isn't particularly fun. Buffing loot behind key doors would be a good start and maybe removing key uses until vacuum exploits are addressed better.
