Taking Viritess's suggestion, I took the time to whip this up. I've just been wondering how those melee skills could come in handy as far as bar space and all that is concerned.
However, after coming up with this, I happened to have read SwordCoheir's post above about the abilities. So, I'm not sure how far this will go. But here goes.
1. Weaponskill 1 + (AOE EnAero + BarAero)
2. Weaponskill 2 + (AOE EnStone + BarStone)
3. Weaponskill 3 + (AOE EnFire + BarFire)
4. Weaponskill 4 + (AOE EnWater + BarWater)
5. Weaponskill 5 + (AOE EnThunder + BarThunder)
6. Banish
7. Scourge
8. Water
9. Silence
10. Bind
11. Slow
12. Poison
13. Paralyze
14. Haste
15. Blaze Spikes or Shock Spikes
16. Temper
17. Saboteur
18. Spontaneity
19. Dual Cast
20. Composure
Plus the WHM and BLM Cross-class abilities.
