The mistake a lot of recent guides have made is trying to appeal to everyone with a single "Here is the best spec, go spec it" attitude. It largely depends on the setup of your raid, your current gear and the boss encounter that you'll be facing that night when deciding your talent build. Instead of telling players to pick up a pre-determined talent build, give them a list of talents that are compulsary (AttT, Cruelty, Flurry etc for Fury...) and then go through all the talents that aren't compulsary (Unbridled Wrath, Tactical Mastery, Heroic Fury etc...) and explain the situations that you would use those talents.
People can use a cookie-cutter spec, but they won't learn and won't understand why they are using the build (nor will they know it's advantages and disadvantages). If you go through each of the talent points that are optional and the ones that are compulsary to a Warrior build then they are going to learn the reason behind each of the talent options and learn. You do not learn through simply copying.
