I'm using SW on a red mage/sw/necro and I'm wondering if I should take the skill above 78. Right now with 78 I get no-fail pixies, and with 106 I could get no-fail wildfire, but why would you take the skill higher. It seems like all intensity/boosts/damage increases/timers come from your focus strength, and that the skill is basically just used to figure if you can cast the spell or not. Is there any benefit to having higher skill or is my "many failures" wildfire at 78 just as strong and as large at the 120 wildfire? I can't seem to find definitive information anywhere, please enlighten me. Thanks!
