Level 24 isn't really too much. Make a new character, and do as following.
Full INT until level 16, then full STR until lv 24. This should bring you to the 70:70 balance. That's a good hybrid. Concentrate on Pacheon, Lightning and Ice. Leave fire trailing if you don't have the SP.
After level 24, adjust your stat points... every time you level up, take down all your clothes and add stat points so, that you have either 69:70 or 70:69 balance.
