You also lose Dragon Kick - very doubtful you can hold up.

When I get bored, I play LNC in endgame content. Did it a bunch at 50, still do it now at 60. You lose 4th hits, jumps, etc. It doesn't hold you back as much as you'd think. The only issue is there's not much good to take in exchange - Raging Strikes is about the extent of it.

Where my DRG can pull 1800+, my LNC can pull 1400-1500. It's a lot easier in 3.2 because all the gear works for both DRG and LNC.

Just don't bring LNC into Midas Savage and you will absolutely NOT be holding your team back, unless you suck at your Job/Class. I still regularly out-dps the majority of DF players in Midas normal, even on LNC. Ran into a PGL in A8N last week who beat the pants off the rest of the DPS, so meh.
