I had 4x lvl 100s, twisting blades rouge, bone spear Necro, nado druid, ww barb, tried Necro first an died at boss fight twice, switched to rouge same results, and so on, the blood seekers would just sack me, switched my ww barb to hota and have cleared up to t5 an still going, initially i thought it was too brtual, but it seems its really only meant for stier builds
