The Problem of strong Mages

mages are very strong. They kill warriors and archers within one or two shots from long distance. This is because warriors and archers have usually no stats on int, so they have low magic defense.

reasons for this: warrior/archer need at least two skills:

 dexterity for hitting target
 agility for not getting hit
 vitality for surviving a little longer
 luck for crits.

mages just need int. So mages can easily max out their needed stats. So here is the proposal: mages need more different stats:

 war magic:    str + int
 astral:      luck + int
 life:         vit + int
 nature:       agi + int
 transmution:  dex + int
