If you want low lvl bounty, go on with 5 def.
If you want to get members (in med crater), you could calculate which quests you can do to get 20 def by quest xp, and become an initiate/mystic pure, try to get as high gloves as possible and mith defender. But it basicly depends on what you want, even a lvl 95 with kids ranqe stats (99 att str hp and 52 pray) doesn't really own in bounty hunter because you will get pwned by lvl 110's with 99 strength aswell with a high defence. It's a still cool account and will have awesome specials, also you could pk pretty low budget, just 1-item and spec people and run, if that's your ambition you could go for that kind of account with 5def. If you don't like that two options go for a rune pure, you won't be unique with those stats but you can own.
