EDITEDIT: I have gotten my achievement, however this thread can be used for other people to ask for help/gripe about how long it's taking them. My achievement was gained through my just giving up and hitting the "Dismount" whenever. No jumping, no teleporting, no summoning, pure randomness - sidenote, I landed almost on the lower edge of the ring and got it (Blood Elf Female). I had landed on people who had gotten it and people have landed on me and gotten it, so not sure what other people did that I didn't. Go figure.
I have been landing smack dab in the middle for 100+ tries at this point. I've tried the jumping technique, I've tried tweaking which way my character is facing. I hear reports this thing is bugged, does anyone have any feedback on how to perhaps "unbug" it for a character? Do you need to jump until you get it (no matter how long it takes)? Anything?
EDIT: This is NOT an "I got it on the first try" thread. That's not relevant, so don't post it.
