Fightclass, 2 spells same type of condition problem

[mael 1]

Hello, I made this simple Fightclass for my low lvl mage. The problem I have is that I have 2 buffs at this level, Frost Armor and Arcane Intellect, my condition on those spells are same, If buff need - cast spell. When the arcane Intellect has higher priority the mage will cast it but not the armor and vice versa. After this I have Conjure Water and Conjure Food both with same conditions.. no difference whatsoever (same condition different parameters). Can you help me with this one?

PS: can you give me tip how to make my mage back up after using frost nova when I aggroed 2+ mobs that are melee?

Thank you very much for helping me with this!
