What should I do with my pure?

Ok I've got a guy with 40 atk 50 str 2 def 44 mage. 1 pray

Should I, A., keep his def at 2 and make him a true pure

Or, B., raise his def lvl to 40 or 45 and make him a rune pure?

Any opinions suggestions etc would be appreciated.

 

keep it at 2

 

Raise it to 5 or 10

 

2, 20, or 45. No point of anything inbetween.

 

lol make a new its best i think.

 

I think i may get 20, see if I like it and maybe get 45.
