In all honesty though there's no real problem here. Some loot drops, some doesn't. It happens. Personally I hate the idea of ONLY the loot in the party's classes drop and I usually use these places to get my pre-50 alts. My lvl 32 Ninja can't run WoD for his scouting gear and my PLD's iLvl of 103 is simply cutting it too close. So my 113 DRG main is what I use to gear every thing else up. And it had over half the poetics gear pre WoD. So it certainly doesn't need the gear (Though the Demon Gauntlets of Maiming did have better stats at the time so I do have those).

The loot system is working just as intended. Yoshida said back at launch that primal and raid drops would actually have a higher chance of being a class that WASN'T on the team at all. But that idea didn't make it into the final draft.
