What is the core concern here? Just made level 7 and this team simply laugh at everything:
BattleMage (Mix Warrior/Fire/Witch)
Enchanter - All Schools unlocked
Jaha - All Schools unlocked
Madora - Added Dex to make he War/Marksman
Each has 10-20 skill options each move.
Teleport is powerful.
Summons is powerful.
Maximizing AP and AP recovery makes players very powerful.
I love the options, but the AI has to throw more at me. That said playing normal, will be starting hard soon.
I think the system is plenty good, the AI just has to be more powerful.
