I suppose I could add more dps from rings but I've had my rings for a long time and like them. Thanks to the forum folks for inspiring me and helping me with some items - I check alot of your gear (quietly =P). Loot 2.0 may make this easy to achieve in future but as Peterbiz says a 400k CM wiz will still be a 400k CM wiz.
Off-topic - I was in the men_with_juggs twitch this morning and a new CM asked my opinion on our Turbo friend's setup of 490 dps. Sorry for not being able to outdps Turbo but he did have only 10 APOC, 461 LOH with no LS at 2.73 aps. In his defence, he carries a LS weapon and Apoc chant in his stash and swaps them when fighting single targets and RD respectively. You decide if you want to do that - I shared my opinion on the set-up on twitch (Dr Neuron was there as a Mod anyway) and directed him to our friendly forums and guides.
