I love CH, because it gives me a way to lessen my damage by using the pet to help tank. I am a Master CH, so I have a level 63 Kimogila to attack with, and take a little damage. Plus they make it easier to single pull mobs. Because of my CH pet and my combat droid, I am still happily solo grouping at level 80, and making decent XP. (Spending most of the time working rebel faction missions on Rori, and getting about 3000 XP/300 combat a kill, not to mention about 8K credits per mission, a little slower then I want XP, but not bad money)
