If you go wizard for instance. A majority of builds put your two damage skills at level 1 and max the other abilities, why? Because they scale like $#!+. Not only do you get a SMALL amount of damage from leveling them up, they consume WAY more mana. So much so it really isn’t worth it to a point where you drain a third of your mana bar for that 60 extra damage. However, if you are going to go rank 3 wizard, you have to deal with having those two weak spells until you get there. This is stupid.
Why does the mana cost increase so much compared to the damage we get? There is something wrong with your game if people avoid leveling up damage skills because it’s not remotely worth it.
