I rely heavily on Toskk's feral DPS methodology for ranking my cat DPS gear. And I rely on the Pawn addon to show me those rankings in-game for quick decision making. And thanks to Toskk's amazing user responsiveness it's now much easier to combine the two.
There's a new feature on Toskk's calculator: a Pawn scale ready for importing into the game. Just go to his webpage, update the form to your stats, then go in-game to Pawn and click "import" to bring the scale in. Couldn't be easier.
Well, one complication: if you're at the expertise cap the Toskk scale will value expertise at zero, which later on down the road may get you in trouble. Same with hit cap. The workaround is to click "Ignore hit/exp. cap" checkbox on the form. Similar problem for meta sockets: unclick the "Relentless Earthsiege Diamond" checkbox before generating your Pawn scale to be safe.
