My objection is I want to leave an impression when I attack something.
That is my objection as well XD
I believe the most firepower you will get is going deep into the Fire tree, as Anobix has inferred. My suggestion would be to use a mix of deep fire with enough arcane tree to get to presence of mind. Presence of Mind and Pyroblast together are a wonderful thing to behold, although you only see it once per 3 minutes.
I think it would be helpful to know your current level and maybe the kind of gear you have. If you are leveling a mage, I recommend fire. The single target DPS is simply insane.
