The main problem of BLM is that you get punished for messing up a lot.

When you move you can't cast, so no damage.

While moving your Astral Fire timer just keeps running, so you now have to replace a Fire 4 with a Fire 1 to refresh the timer, wich means you further lose damage.

If you was moving out if your Ley-Lines you also will lose damage. With a bad timing on the Ley-Lines you can waste them completely.

When Enochian drops you are really screwed and basically have to restart your rotation with a weak 3.5 seconds cast. Bonus points if it happens right after you have used Enochian, like in the opener, you are now stuck in the 2.0 rotation!
And of course you lost the timer for your Polyglot.


While the job is actually not that hard to play, one mistake can lead to a cascade of damage loss >.>
