So yes the latest version of Rawr has a rogue module. To sum it up in one word I'd say it's, incomplete.

The numbers are wrong in some places. Especially when I saw it start suggesting to use strength/crit gems. Looks like it tries to calculate dps based on a 4s/5r cycle, which you can't change, instead of suggesting the ideal cycle for your gear.

It's definitely vastly underestimating dps, example myself it has me doing 1000 less than I have done and what spreadsheets are telling me.

Current spreadsheets do give a few more tricks. Proc modeling, CD timing usage, energy pooling, etc. Rawr doesn't have those fancy features, just a bit of average stat modeling.

On the plus side, it does look prettier than a spreadsheet. Probably much more intuitive to use. But currently, at best it's a glorified version of http://shadowpanther.net

You can get some rankings of gear (where it's not just plain wrong), but don't trust the dps numbers it gives.

One thing I may not know how to do is have it filter out gems I would never touch. Like it suggests even INT gems in gear that's superior to mine's. I don't need to know every possible iteration of gems in the sockets.

Well this might have potential. If they're able to "steal" the formulas and the cycle/proc/energy modeling from the existing spreadsheets. But with patch 3.0 getting close, there probably isn't much time for that. I'd think I probably won't look at this again til a level 80 version comes out.
