So I did a heroic and was sorta surprised to see my dps being strangely lower than pre-patch. I checked out my meters and it seemed like I was just getting way less crits than expected. At first I just assumed it was bad luck, but then I went and did some dummy tests. On both (5 minute tests) I did with flametongue glyph my crit was decidedly lower than normal, actually even lower than what I would have without it. However on the test I did without it my crit rates were fine.
Nah, I'm elemental. I know it's not supposed to be better, but from my own tests with shocks rotations etc I actually found I performed better with Flametongue over FS glyph. Might change with the new Rolling Thunder changes though.
