I got rid of parry at 49 because I was going oom quite a bit, but at 29 you should be alright. I'm thinking about going back to having parry, but with the spec I run now I don't have judgements of the wise either, which used to help a ton with mana.
I didn't get it at all, I really don't need it in all honesty. I don't run oom too often, but I do run oom a lot more often than I did when I had it. Which, when I had it I never ran oom. Instead, I'd usually die with like 90% mana then ever run out of mana and die because of that, so I figured I no longer needed it. When I respec'd I tossed points in increased crit chance on judgements because I was going for a more judgement intensive spec, but I kind of wish I dropped the 2 points in imp BoM for eye for an eye.
