Spell penetration and Expertise
So, since the new core doesn't seem to be coming anytime soon, I was wondering about spell pen and expertise on this server.
Seems to me, spell pen doesn't do anything, I don't get any resists / no notable differences in damage with or without it being capped.
Same goes for expertise, but I'm not entirely sure how to test this properly.
Has anyone any more info whether or not these stats are doing anything at all? Or is this another bugged thing we have to live with for now?
