What are your impressions?

BTW, I think Grenades do have a use: I use them as AoE that gains hatred while I kite/dance around champion/elite packs. I dance around the pack, drop (cluster) grenades in the pack's path, and gain hatred for bigger damage skills while I'm at it. So in Normal, they weren't a lot of use, but in NM, I'm finding a use for them often.
