Someone needs to tell Faction that you don't need a phD in Mathematics to teach people calculus. Taugrim is a teacher, Faction.
Personally, I'd avoid using words like "pro" or "elite" since they are loaded words that are almost always going to bring flames and trolls. There are some things that just can't be taught via guides. Things such as reaction speed, field awareness, and intelligence.
What Taugrim does well is teach the things that can be taught. His guides are excellent for helping those who are transitioning towards proper keybinding and strafing. They are also good for people to start building a correct PvP acumen. His guides are targeted towards players wanting to do well in warzones (battlegrounds). They are not targeted for professional tournament players, obviously.
