You're missing my point, within FF there are not Multiple builds, you have your kit as you see it not changing. In WoW there are choices in the abilities you use, not everyone HAS to play the same, and you will not always be using one ability or small amounts of abilities through an entire run. While some classes in the tank role can be built to revolve around low CPM and only using a small amount of your abilities, you are not locked into that type of gameplay.
