I used to use his profession guides they really did help in the pre cata days (before WoW professions site was around) It's really up to you he does keeps his guides up to date and he does he homework (I still get emails) Their are some free leveling power leveling add ons to help you level much like the paid guides. Keep im mind I think he moved to a sub based plan and not a one time payment
the guides work great for leveling almost in autopilot, also the zygor guides work great, the only problem is that this 2 companies moved to a monthtly fee payment model for BFA, not worth the money that you are paying if you ended up paying almost the same as the game monthtly subscription. Recently there is a new free addon for leveling in curse addons webpage that do this without the payment, is not as advanced like the pay ones but works. i will leave the link below. We need to support this kind of free addons.
This Addon solves that issue where you have 5 Paladins in your Raid and no one can decide who is Buffing what. It has a little UI that represents Different Classes in your Party or Raid. You can change what buffs you want to give out then just mash the Class Button for each Class type until they all Turn Green. If anyone is missing a buff you are assigned the Class
I've used WoW-Pro for years and in WoD, Legion and now BfA it's been awesome for just going on auto-pilot and working your way through a zone. It has 3 levels of depth you can set, so you can set it to just do 1) the main story, main points of interest and rare mobs and treasure that aren't far off the beaten path; 2) every quest with a more thorough dive into the side stuff; 3) absolutely everything.
