Also haveing multiple schools is nice but to have 2 at fifty vs 1 with intisify up and all the big aoes would be bettter imo. [/quote]

I think having 1 at 100 is more important with intensify. That way you get your rank 90 nuke and a 100 aoe. Tip though if your going for 100 fire I think leveling wall of fire is a waste of resources since it is on the same timer as volcano and does allot less damage. I leveled my wall of fire to 75 and would give anything to have those regs back to finish taking my volcano to 75.
