This is meant to be a simple rotation and can not be used for every situation. This is just showcasing the basics with massive crits and showing off some burst damage. This video will not get you to the top of the dps charts on Ragnaros, nor will it get you 3200 MMR, but if you are rerolling a paladin, or you are a noob then it might help you out.
Plus the music is awesome.
Please thumbs up the video if you thought it was helpful, and if you realize that it was a "simple rotation." Also thumb up if you are a pro paladin and you did not learn anything, but enjoyed the music.
