Over the past two days I completed my 16 runs on the Jailer. I did them all solo, I have those characters gear up well enough to do this (I have had better luck outside of raids).
On those 16 runs, I did not get the mount. Over the past couple days I have seen posts by people on social media showing off their mounts and saying it took only a couple runs, even some claiming it was their first attempt. Congrats to all those people getting their mounts.
As RNG goes, you will have people getting those mounts in a few runs, you will also have people needing 40+ attempts as well. My warning to everyone is to not get your hopes up, you still have over a 94% chance of NOT getting it with every attempt. And with most of the mounts, there is a weekly lockout, so you are looking at 4 attempts per character during this event.
In my above example, a person with a main and 3 alts would not have gotten the Jailer mount during this event. Stay positive, but be prepared for disappointment. I have 48 more attempts left on the Jailer mount.
