Guess i was luck then, havent noticed the tattoo bug on my dh and i was able to do aggramar and argus on patch day just fine.
Fps i didnt noticed aswell, in fact i was really happy that they finally fixed the loading screen of dalaran and other areas and i just used moroes and ..dunno, everything looks in order xD.
So yeah, i think most of the issues you said are fixed by now or will be fixed by tomorrow.
Edit: nvm on the moroes thing, noticed that on a fem gnome, looks like they lost their middle toe.
