It entirely depends on the enemies that you are fighting. I can fight up to orange on a new class without too much of a problem by bringing in abilities FROM OTHER DISCIPLINES.
The key here is that you need to mix-and-match things that are useful. IE: Bring in Scourge, Slow, Gravity, or Cure from THM/CON to augment your developing discipline. These extra abilities will prove useful as well as the pure HP/MP buff from having a higher Physical Level.
Combat is much less about "spamming spells" and much more about keeping yourself open to change tactics when needed.
