@ tiamats - BTW my BP is lvl 70 um and has over 1400 def and 2900 attack, so I still advocate REC in your build.
If you just link REC 6/7's you can get this, but at lvl 70 you will be hit hard if you pvp and higher def is a must. I would advise if you go BP, link life 7/safe 7/mystic 6&7/Abs 5&6 in every piece or the comparable in the helm and top. Example Forbid 7. Life 7 is better than safe 6.
I am full INT, linked INT/REC (I'm sure I mentioned that already). I less def and attack than you, meaning you are linked better. I only have one 7 linked in my main gear (one of my off-weapons has a 7 linked, but I don't use it. Poo). I am trying to link more 7's, but I broke SEVEN 7's (5 Assault and 2 Mystic) with 32% chance on bonus linking Sunday. -_- That being said...I can't really afford Life 7's, though, and I prefer Mystic/Assault 7 over Absorption 6.
Basically, I prefer attack over defense, in general. And here's why: I can't PvP. I'm too poor. I don't buy hundreds of dollars of AP a month. My advice is or other poor people, not for uber rich. Uber rich people pretty much don't need advice, and if they do, well then you give it to them. I want more attack so I can farm and plvl faster, which is how I make money. The REC/absorption I have makes it sufficient for me to tank. I have enough, but not too much. Right now, I'm working on my attack power first (linking a Mystic/Assault 7 into my weapon) so I can farm even faster. I'll start slowly working on better gear after that and eventually work on more defense, absorption, and HP.
When I can afford an Iron Princess  linked Swift, 6/7 Mystic/Assault, and ele II +15...THEN I'll worry about reconsidering my build and if restatting with more REC would be better.
Let me give advice to the other people who aren't uber rich. You worry about advising the uber rich. Thanks.
