Keys loot rate change ?

[Bul4]

Hello i just wonder its a bug , real change or just my bad luck. Last times i notice that loot is highly reduced just after all last problem with arena/connection problems.

Gold key giving me like 80% used SoT back, when now after couple keys i did get nothing.
Frozen key giving like 50-80% of ironite used for SoT now like 5-10%.

RNG luck is always possible, but the Frozen drop rates over 1000 runs and several keys were surprisingly consistent. If an actual nerf has happened, it should be pretty easy to track. Will take a look next time I run that dungeon. Would be incredibly disappointing if they reduced the ironite returns, as it is a dungeon aimed at being a catch-up mechanic for newer players.
