Took a quick look, it seems ok for really new hunters, but as someone who has played for a long time I kind of laughed at the information. Keep in mind, soloing with a hunter is much different than raiding, and both of those things are much different than pvp. Macros are a big part of hunter mastery, and having good keybinds for everything. I would also like to note that, with some finesse, having a good melee weapon to swap to (with help of a macro) is very valuable. Most of the time your melee weapons are just stat sticks, but when you get up close and personal you can quickly swap to a big, slow 2h weapon and do a lot of damage with a raptor strike! Works well in soloing and PvP when you are not always at range. For raiding, you should never be meleeing really.
