I have the same question, or are they even going to fix the ones that were already purchased? :\

Sure, it's annoying when they're on a ledge in huttball sometimes, but most of the time there's someone next to them that I can charge, and besides, I do love a non-moving target.

Without any type of healing from a companion or annihilation dots, try preventing more damage using interrupts either immediately on channeled spells, or wait until near the end of a cast bar for a regular casted spell so the mob wastes more time on casting and less on hitting you. Also try throwing up an obfuscate soon after you pull. Intimidating roar works great too after a charge and smash on all the mobs. You can try having Jaesa off-tank a single mob while you are on the others, or send her in first. Besides charge into savage kick, and smash into pommel strike, you can force scream and then pommel strike too.

I started leveling a sorc, and she is still lower level, but I'm pretty sure it must be the most op class for soloing harder mobs and quests. Bubble, heals, damage, and cc, and a pet to tank for you. CC is the most powerful thing, next to being able to heal. When I was leveling my marauder, I was able to do all my heroic 2, heroic 4 with droids, and a few without droids. I don't know if it's possible if you're not annihilation spec for marauder, because the heals from dot crits seem practically required, especially while killing the first one or two mobs of each pack. Also I'm biochem, so having the reusable self/companion heal medpac made a big difference since sometimes I needed to keep 1 mob on Quinn, or it was too much damage on me. Using it will res your companion if they are dead too. Hardest packs were those 5 gold, 3 gold/2 silver, 4 gold, and then anything less wasn't too bad. The interrupt/obfuscate talent helped a lot too, especially for champ mobs. No video but I have a couple random screenshot. http://imgur.com/a/KHtd7
