Question is in the title. I have seen this point brought up a lot recently. Personally I can't remember the last time I learned a mechanic from a normal dungeon or even a normal trial. Typically the sharp contrast of difficult content and easy content in ESO and the lack of a proper medium or progressive difficulty makes running normal content to learn mechanics useless. You are far better for pushing through vet if you want to learn mechanics.
