If you want to use this account on bounty I'd say don't get def at all or train it to 45 by doing quests (use a rune pure guide). 70 def is pretty pointless unless you dare to risk karils or ahrims in bounty. Much people are ruining their pures after the update but bounty is pretty good if you get an account like kids ranqe had. 99 att, 99str, 99range, 99magic, 52 pray and no def. You just go in bounty with a team, use runec'bow with like diamond bolts and maybe a few d bolts. If you see an enemy attack with rune c'bow, if they try to run (or try to dds spec on you) barrage/blitz them and get your dds spec for the KO. You'll be like 95 cb and that's ideal for the second 55-100 bh game.
