Put it this way, at a Submerged level game, the average non-monster, non-wizard character will probably be rolling attack with their apex skill at 5, with, at best, a Weapon:3 weapon, more often Weapon:2, and their weapons probably won't be getting much stronger barring Refresh-costly powers--and even then, they can't do much to raise their accuracy. Plus, they have to have the weapons with them.
A wizard, on the other hand, can very easily be regularly casting Weapon:7 evocations, rolling from 7, in their preferred element, barehanded if they put their Refinements toward specializations instead of focus items.
So given a Good dodge roll, that non-wizard's going to be hitting for around 5 shifts of damage, while the wizard's going to be hitting for 11. The wizard will only be getting stronger and more accurate, while for the most part unless you're a plot device, your attack skill will top out at 5, maybe 6 given a stunt.
