I would like to see some kind of limitation of the RNG. I am at my 250th solve for Tol'vir mount, and I'm fully aware that I might have to complete 250 solves more and still have absolutely no guarantee of getting the mount whatsoever. I could also do 2000 solves and still be without the mount. Now, this is fine for dungeon runs and rare drops from end bosses, but this is a profession. Sure some luck is involved in for example alchemy with mastery procs, but this isn't at all as dire as hoping for a 1% item to pop up.
