Well the legs that drop their aren't that bad. Last time we cleared the instance we got those BS legs on Grand Vizier and Those PoM legs on Omni-prophet. The BS one gives a good ratio between heal rating and DPS, i don't know much for the pom stats.
A friend told me he looted Those legs On trash mobs. They are nice. As much armor as LL hate increase legs with less HP but more DPS than tiger legs.
But it's true the other epic items in there didn't seem too appealing. Anyway you need TS for sure. The grand vizier is super easy during the first phase with one guy saying when to stop dps and when to move (everyone is on same timer). And Second phase is easy aswell if you put a guy slacking at distance announcing the stop dps and the new colors. He'll take the ruins so won't affect the groupe by the AE and DPSers and healers will only have to worry about colors.
The last boss without everyone on TS is something worth a kick from groupe ^^
No one will ever force me to explain that tactic in groupe chat ! It's already tedious enough to explain on TS ^^
That being it's true they could adjust the blue items better (and maybe epics too didn't really look at them closely). Haven't seen all of them but main thing is the super low base dps of all the weapons because besides that they have great stats. Rise it a bit and you have very decent blue weapons that can actually be usefull to some.
