Well like I said - do you like attacking, or supporting?
A highwizard will almost always use an offencive spell, unless their using safteywall.
Scholars on the other hand, will use supportive spells, that benifit your party.
For example in Woe:
On a wizard, your main jobs are to force people to put on GTB, and to freeze people, so that
Champions and Creators can AD frozen targets. (also mob displacement)
On a Scholar however, you'll be endowing your party members, using magnetic earth under the emp (while you attack)
Soulchanging teamates. MG'ing narrow choke points on attacks, and other various things.
Personally; the only offencive move I use in Woe is Soulburn. (and Heavens drive, But thats only to reveal stalkers)
