The BD Warlock pet is supposed to cast both a snare+DD and a LT. It appears to do both, but no health is returned when the latter is damages a target and the pet is not at full health.

Repro steps:
1) Make a 50 BD
2) Cast a command and warlock
3) Pull a yellow mob with the pet attack command
4) Wait for warlock to get aggro and hit
5) Pull aggro off warlock so it can cast again
6) Watch warlock's health bar
