BLM hotbar controller

Hello. I am trying to figure out my hotbar ahead of time for level 70 (level 60 right now). Want to get muscle memory trained early.

There are a few skills I am unsure how often they are used. For example, bliz 1 and 4. Scathe. Just curious what skills are safe to remove, and which aren't used much at all.

For role skills. Addle, Mana Shift, Apoc, Diversion, Swift?
