It seems to me that hybrid builds could still use a bit of a buff. If not in terms of raw power, at least they could be made more interesting. I have the following idea for a support skill to fix that.
Arcane Manifestation increases the damage of only melee skills (so not for normal attacks) by a percentage of your MATK for a relatively long duration, or as a toggle that slightly reduces energy regeneration. However, this buff should be quite modest. As you deal (melee skill) damage with the buff activated, the arcane powers start building up. Once the powers are charged, you can unleash a very powerful attack of which the damage depends on MATK. The build up goes faster with more ATK and more damage dealt (with melee skills), and goes slower the higher your level is (to prevent instant charge at higher levels). It should be so that with very low ATK it is impossible to reach full charge, and with low MATK the unleash is not really worth the trouble. This way you can play with finding an ideal balance, and this allows for a different type of playstyle.
So basically it starts as support, but in the end becomes an attack if you use it well. The unleash of power could be anything really, as long as its awesome.
