One thing worth mentioning : The last bosses of SP and Ramp aren't just 1 extra badge each, they drop descent elemental shammy epics.
Another boss worth farming is the first boss of MGT. (yes normal is a pain to do for the attunement) He drops a really nice dagger.
The trash is a real pain until u get it right, but doable. The boss himself is also pretty easy, i let my tank build aggro for 3secs, then pop fire elems. (GotN on the tank here if draenei) Then pop heroism, and start DPS on the crystal the second he starts drawing from it. (you should get it down before he reaches 40%) when he starts AoEing, tank him in your group and do a couple of chain heals to keep the group up. He should be dead by the time he is done drawing from the second crystal.
This is the heroics i farm each day for epics and badges. If i have time for more badges i do botanica.

Another great tip in general for heroics is that you have ALOT of heroism/bloodlust use them on any pulls with 4 or more mobs. You only need a maximum of 2 on a boss anyhow.
