seemed any better than the others

I wouldn't say any of them seemed any better than the others. I like that they're all fairly simple and pretty much just go over the spec's core abilities and how they work together- it's enough information to give you an idea of what you should be doing, but not enough to be overwhelming for new players. If you want to go in-depth there's always sites like Icy Veins, Noxxic, and other YouTube guides, but if you're acheter wow gold just trying to get a feel for the basics, these videos seem like a good jumping-off point.

My suggestions to improve these would be also covering which stats are the most important, what mastery does for that particular spec, and of course, make one of these for each spec. Maybe going over major cooldowns and defensive abilities too.
