Discussion for Creepy Crawlers!:

So after killing Majordomo the only heroic mode left in Firelands, for us to unlock Ragnaros heroic, was Beth'tilac. We had waited with even pulling this fight in heroic mode because the rumours were that it would be the hardest of the first six bosses. After spending some time wiping it was clear the rumours were true. It was absolute chaos with no signs of progress. Then we slowly started getting better at handling the spiderlings and kamikaze spiders and it started to look like we could maybe pull off the encounter, or at least pull off the first minutes! It took a few resets to start seeing phase two with any regularity and we had a few wipes on very low percentages, where it would have been a kill with just a bit of luck. Then finally we had a night where everything just worked, and finally the big bad spider was dead!

It's certainly been the fight we spent the most effort on progressing though the heroic mode on. Worthie even got a special Beth'tilac spec! And we didn't even have to pay her 80 gold to do it!
