I personally don't like starting a new job with like 30+ skills I'm not familiar at all. So even when SE introduces new jobs that for some reason starts from 60, 70 and in recent expansion 80lvl, I ALWAYS take them do deep dungeon and start from lv1 there, so I could be introduced to all it's skills slowly and one by one. Also, I'm personally like gameplay at lower levels when everything is much simplier and there are no complex rotations, therefore I'm absolutely against getting all the skills at lv1.
