02/02/2012 11:10 PMI probably wouldn't take this advice, I'm sure Blizzard will be nerfing the drop rate drastically (100% to 1%) to ensure that a relatively rare mount remains so. They've done the same in the past with Invincible and Mimiron's head.

While blizz will probably nerf the drop rates, both Invicible and Mim's head do not have a 1% drop rate, but, rather, is closer to 10% (Invincible is shown as Very Low, which is around 5-10%, and Mim's Head is shown as very high, or 50-70% drop rate. Various reports also suggest a similar drop rate, with most ppl reporting about 1 head every 1-3 kills, and 1 horse every 10-20 kills) Even then, both fights are significantly harder then Ragnaros in terms of mechanics, and must be done on 25 mode. The majority of the fights on heroic mode become easier to clear as one acquires more gear. With Ragnaros, the majority of the one-shot mechanics can be outgeared, and become easily done with time. Gear wont prevent ppl from going insane or being thrown off a cliff, but will prevent ppl getting one shot should 2-3 Sons reach the hammer. If dps increases by 100%, as it tends to do from expansion to expansion, it is entirely possible to down the first 3 phases without having to worry about seeds/traps/meteors, and during the third phase, it is a simple matter to move Ragnaros into roots, and quickly move away from him when needed.
So, while he would have a 100% guareented chance to get a mount should he buy his way through it, he can save his gold and probably run heroic Ragnaros a mere 10 times next expansion in order to get his firehawk. With the ability to get it in 10 man, the purple Firehawk, the title, and the flametalon all up for grabs, it would be a simple task to get 10 ppl to help him get his mount. Just sayin'
@OP, check out http://www.wowprogress.com/pve/us/nordrassil, look up guilds that have cleared Ragnaros heroic, and talk with members of those guilds until you find an officer who will get a raid up to run you through.
