I've been running archaeology digs, farming for Winterspring Cub Whiskers, and grinding Tol Barad while waiting for running normals recently. I recently bagged a Scepter of Power and traded in some JP for the Apple-Bent Bough. With the off-hand intellect enchant, I think I come out ahead of my old Staff of Siphoned Essences. Here they are compared on WoWhead, though it misses the +40 INT from the off-hand enchant. That with a few smarter enchants and though my iLevel is the same, DPS should start looking up. I also traded out my one piece of Heroic gear, the Corrupted Egg Shell, for the normal Gale of Shadows I picked up in my tenth or so run of Grim Batol last night. It was time to stop worrying about convenient mana and to throw in on more DPS.
But the real lesson for my grind comes from
this comment on Baradin's Wardens at WoWhead:
You can do a maximum of 18 daily quests to earn reputation with Baradin's Wardens [A] or Hellscream's Reach [H].
The post continues to tell you how. I've been stopping after "6 daily quests (out of 22) that you can pick up at Baradin Base Camp [A]", when, "If your faction controls Tol Barad, then there are 12 daily quests that you can pick up at Baradin Hold." Whoops. 18 a day (even the more sure 12, since I won't check in that often) would speed up the grind for the Stump of Time just a little bit!
