I could be wrong about this and plz let me know if I am but I've noticed there is a bit 
of extra mana drain depending on your intel level. For example, if a spell was heavy 
concentration at 15 intel but becomes moderate concentration at 20 and up, the 
moderate held spell grants less mana drain for each tick. Now my question is, if a 
spell remains moderate at 20-25 concentration, would a person with 25 intel actually 
experience less mana drain per tick than a person with 20 even if the spell remains 
moderate for both people, or is it essentially the same?
You noticed wrong. Mana costs for spells is determined by the spell. What that translates to in terms of percent drained per tick of spell is determined by wis/mana, since those things determine your total pool of mana.
