New gear has very high resists so maxing your damage is a must. That said, putting a mystic 7/6 in every piece of gear is a must. Now what do you lapis? A mystic 5 or something else? Even if you link a mystic 5, you still have 3 more slots.
A level 7 fortune lapis adds almost as much damage as a level 5 int lapis, more when using the wrong ele, and less when using the right ele. Plus, it adds crit rate when etain bless is down. So I see no reason not to link a luck 7 despite what the above people say. That leaves you 2 slots for survivability.
If you want to be able to DPS bosses without pulling agro off fighters or tanks, low rec is a must. Thus, survivability should come from absorb and life, not rec and defense.
Perfect all purpose gear link in my opinion... even if you use EB most of the time is:
Int 7/6/5 Luc 7 Life 7 and Absorb 6
Or int 7/6 dual int 5 luc 7 abosrb 6 life 7 (Same damage, 95% crit without EB)
Or int 7/6 luc 7 life 7 abosrb 6/5 (Survivability I guess)
If you only want to PVP, you can substitute in safe lapis.
If you only want to PVE, I'd do int 7/6/5 Luc 7 Dual mystic 5 and life 7. You'll hit hard and still have a lot of HP at least.
Wasting 200-300 stat points (however much you need) for "oh gosh, what if I die and lose EB oh noez" isn't worth it.
I disagree, "wasting" 200-300 luck to get 80-120 more int is truely a waste.
