Just look at the stats.... I'm guessing you are choosing between the AF2 Warrior body and the +1 Bravura, correct?
If so its like this....
Here are the stats for the NQ Bravura + HDL body (Keeping in mind the body also covers the head slot).
44 DMG
262 Def
60 str
66 vit
76 parry
30 crit
Skill Speed 23

Here are the stats for a +1 Bravura with the HDL body
42 DMG
64 str
262 Def
71 vit
80 parry
30 crit
Skill Speed 26

And lastly the NQ Bravura with the Af2 body and the Hoplite head you'll have to wear, since there is no DL head piece.
44 DMG
264 Def
66 Str
74 Vit
68 Parry
23 Skill SPeed
39 Acc

At 262 and 264, the defense is negligible. But it should be noted that the AF2 wins by 2.
The +1 Relic will net you 2 more damage than the AF2 body, but 2 less STR. Damage > STR so thats a win for the Relic +1
The +1 Relic nets you 3 less Vitality than the AF2 body but 12 more Parry . I'd chalk that up to the +1 Relic as well.
The +1 Relic will net you 3 more skill speed than the AF2 body. 26 > 23
Lastly, the +1 Relic will net you 30 crit, while the Af2 Body gets you 39 ACC. If WAR was a whiff class like it historically has been, then the ACC would be a bigger deal, but as it stands, no one really missed (unless you personally feel you miss a lot, but I don't see that happening) so statistically, the 30 crit is better. Another win for the +1 relic.

I know, I know... You don't have the HDL body, so you're thinking the body would be a much bigger upgrade.... but since tomestones of Philosophy aren't capped... I'd strongly recommend the Bravura +1 and HDL body. I just think you'd get the strongest return on your investment.
And to anyone saying Tanks shouldn't get the weapon... I think we just showed them!!!!
