It would be nice to mention that these guides are focused more on easier gameplay than maximum perfomance. I play Arcane mage whole Legion, I did few #1 parses so I know what Im doing, but some things in Arcane guide are pure convinience and not for good troughput. Like taking Incanter for m+, you can still get more from Rune of Power + Overpower than from Incanter/Orb. Also mastery is worst stat after you get a bit rating, even without kilt, but it makes rotation much less punishing. So you could mention this so new players dont take this as best thing you can do. Otherwise great job!
The 2nd paragraph clearly states:
Maybe its because im too big tryhard, but my understanding of pargraphs you cited is that these guides doesnt include "in depth" things, not that "these guides include things which are suboptimal no matter which content you do, but they are far more convinient to use". Anyway, if casuals understand these paragraphs like that, its completly fine.Good luck with new classes/specs :)
