I distrust all Theorycrafters. Cookie cutter builds, while they may be efficient or powerful, are also boring and pedantic. I prefer to play for fun. Theorycrafting takes the fun out of the game, which makes baby puppies sad.
Theorycrafting is it’s own enjoyment. If you don’t get any satisfaction out of learning the ins and outs of your class and sharing ideas with others, you’re doing little more than messing around aimlessly.
Builds only become cookiecutter when people with little imagination latch onto a thought out build without trying to make it their own.
