Warcraft fights can be explained in two sentences

Do you ever noticed how if you're playing World of Warcraft and you go to a raid, there's always that one raid leader that thinks they're really good at explaining things, but usually loses your attention somewhere around the ninth piece of useless information. It usually sounds something like this:

"OK so in stage 1 he's going to come down and then we're going to DPS and make sure the tank doesn't overaggro, this means that mages and hunters need to watch out because ranged is really good on this fight. What you need to pay careful attention to are the sparks, because if they get to him they will cause him to enrage and he'll kill the raid. Now the fight comes in three stages and the important thing to know is that the second stage is the hard stage and the third stage is hard, too, bust mostly because you have to manage your pool of energy and make sure..."

I counter that the fights can all be explained in two sentences. Example, Malygos:

Sentence one.

"Pew pew a lot, shoot the sparks when the come, hop from purple bubble to purple bubble when they come too, but not to early."

Sentence two.

"Healers be ready to heal while you're in the air, and everybody watch your energy on the drakes, because you'll need to have energy for a shield at all times when he does his super attack."

Why does everyone have to make things so complicated?
