yeah, isn't it irritating when we answer that way? mostly its because heroics aren't all the same. you can do the easier heroics with about the same stats as kara (which is a good answer since dilbert says a lot about pre-kara requirements in his guide). some heroics are gonna be a bit tougher and you might want to have higher stats...
but, i'd say for SP, Mech and Bot and possibly a couple others kara stats are adequate:
1000-1200 +healing
9000 mana
80 MP5
15-20% holy crit rate
BM, SL and other tougher heroics you might want to have a little higher sats.
i'm writing from my phone so i can't look up your armory to be more specific for your stats. and any time i've looked up your armory in the past i've always got an armory error...
