Out of curiosity, is there currently a raid phys mastery damage % cap? If I stack, I can get up to around 2469 agility, 32k phys mastery (109%/108% and some change), and 9.7k crit rating, but I don't really notice any significant boosts in damage. I do notice a lot more crits over other setups, but the damage itself isn't too much higher. I'm wondering if there's a certain point where gaining additional agility and phys mastery is pointless (or gives diminishing returns), so I could start putting points into vitality or other places to try to increase morale or tact mit.
Another weird thing I've noticed is that if I run my agility setup (2401 agility, 571 vitality/8k morale with motivating/banner), I actually get a 6% increase in tactical mitigation with more agility over having more vitality. As far as I can tell by the stats on the gear I switch out, I'm only dropping vitality/base morale and gaining agility with no base tact mit added. By the stat tooltips, I'd assume that losing vit = less tact mit, but apparently not for some reason.
With vitality setup, my agility is around 2260, but I have 10k morale (with motivating/banner) and 6% less tact mit than if I were stacking agility. I'd always assumed that more vit = more tact mit, but apparently this isn't the case for some reason?
