Easy mechanics but you're counting on your entire group to not mess up.

Our last week of attempts (we haven't killed it yet) - we sometimes reach twisters after killing the big snake, most attempts the big snake is still up.
And those few attempts we get into twister phase - either a healer or the main tank dies because a healer was stunned by dreadknight, etc

Its a mess and I'm pretty tired of the fight, its not well tuned. Its just plain annoying the first half is way too boring, redoing it each time is killing the fun out of this game.
I do everything correctly on my end except after 3 hours when I lose focus and miss a divebomb or a conflag/fireball because its been THREE HOURS of attempts.
