[2020] Chest Mount Drop Rates are horrific

Hey devs,

Love the game, been playing since day 1, I also need to know what the mount drop rate is in dungeons, I've been trying to get these mounts for the 2nd campaign forever, with 0 luck. The only real way to finish this campaign is to buy all these mounts, which is an incredible amount if starseed.

So what the f*ck? Is the drop rate like 0.1%?
