I'm running as Destro/demo counting on the fight and I have a Heroic BRF Tier chest and I just got a normal BRF tier shoulder, but I had on a Mythic Highmaul shoulder which has bis stats on it, basically ilevel 685 tier chest, 670 brf tier shoulder, 685 highmaul shoulder.
Is it worth it for either destro or demo to take the lower ilevel shoulder to get a 2pc bonus going?
Also where does the 685 level 4 crafted trinket sit among the bis trinkets? I notice that only raid drops tend to get mentioned on dps charts.
