Thank you for trying to being polite. I know being rude is much more fun 
OA isn’t the sole criteria for strength. It’s low on OA, but it clears its targets with ease. I agree that it doesn’t have greens.
By what criteria? Greenness? It has 2500 DA and 1700 armor. If greenness is your main criterion, you should make that clear somewhere. You should also make clear to what level you farmed the greens. 1 rare maximum? 1 rare minimum?
And, since you’ve tested everything, what’s wrong with this one? (ps, it now does nearly 50% more damage than when initially tested with the buffs)
