Rawr 2.0.3 crashes when using the Mass Gemming feature to delete all other variations:

System.NullReferenceException: Object reference not set to an instance of an object.
at Rawr.Character.IsEquipped(Item itemToBeChecked)
at Rawr.FormMassGemReplacement.OKButton_Click(Object sender, EventArgs e)

Edit: happens both when no character is loaded and when one is loaded.

Do you have any use for a C# developer on this project? I'd like to contribute if at all possible, but all classes I play are currently spoken for. I could lend a hand wherever necessary though if you'd be willing to entertain the idea =)

Should the models be accurate at level 80, or is this just meant to update things at level 70? I'm using the Tankadin model and defense appears to be inaccurate, showing that I'm at 485 def at level 80 in level 80 tanking blues.

Also, the Chance to be Crit tool tip doesn't appear to be working correctly. It says "CRITTABLE! Short by <nyi> defense rating, or <nyi> resilliance to be uncrittable"

Just checked the latest version from SVN it's still seems to be broken, when a character is loaded it doesn't crash but doesn't delete any "wrong" gemmings. When a character isn't loaded it still crashes with the same message.

It is sort accurate for 80. Most of it should work, but it hasn't really been test. Good point with the defense display, currently it just adds 350 to your defense from gear, so you can just add 50 to it and it should be the right number. I forgot about the defense thing not work, when I was originally updating it I didn't have the level 80 coefficients so I left it as nyi (not yet implemented) and totally forgot about it. The next build that gets released level 80 will be assumed for all characters.

I am confused why Rawr Hunter version is showing two distinct differences in upgrades for my toon. I am hit capped, BM build. It shows Belt of The Silent Path as a huge upgrade over the Belt of the Black Eagle, where the DPS Spreadsheet has always shown the opposite. Same thing with neck piece. Rawr says Sin'dorei Pendant of Triumph is better than Shattered Sun Pendant of Triumph, where spreadsheet shows the opposite. Any ideas on why?

Version 2.0.3 doesn´t get the hunter talents right yet. Focused Aim doesn´t include 3% hit (but Surefooted does), which might explain why it overvalues that belt with hit rating on it.
Also Scatter Shot, Readiness, T.N.T. and Surefooted need to have their position in the tree fixed and a lot of other talents in general need to be updated. Basically the talent tree is still stuck in an older beta build version mostly invalidating any conclusions it draws.

All talents are implemented based on the latest build, including Focused Aim. How do your hit numbers look like with each of the belts? There is also a possibility to show relative stat values. Hit rating should show a zero there if you are hit capped.
If you want you can send me a character file (contact me via pm or the Rawr Issue Tracker) and I'll look into it.

Regarding the pendants: The Shattered Sun proc is not modeled. I focused on the changed hunter mechanics.

It sounds like you're saying Rawr has built into it the assumption of 3/3 Focused Aim, and if that's the case, then that would explain the big difference. I have 50/11 BM build, with not talents in Focused Aim, so my cap is 142. I have 145 hit with Belt of Silent Path, with only one Glinting gem for hit, but with Belt of the Black Eagle, my hit is only 127 with same gems, and dps spreadsheet shows total dps almost identical. If I put in hit gems to get back to hit cap, then Black Eagle belt is about 5 total dps better.

Hope this gives you the info you want to check the rawr/dps spreadsheet difference.

Your glyph selections appear not to be saved, so when you load your character template, the glyphs need to be reselected every time. Possible to save them as well?

So you´re saying the talents are actually calculated correct internally even though the description says otherwise? Does that mean if I put 1 point in Scatter Shot in Rawr I actually get Readiness (if it´s considered yet) and if I put 3 points in T.N.T. I´m actually getting Surefooted too?
