I'm playing s sith jugg level 32.
I recently got an apprentice (i wont spoil to those who didn't get there yet)
I found it that with my 2 older companions which were "vette" and "quinn" that I didnt manage them at all, both vette and quinn are ranged companions and i as a sith jugg would leap in to close combat situation leaving them behind for fire support and in case of quinn also healing capabilities.
As soon as I got the apprentice I begun taking her to more and more missions, and since I dont have quinns healing capabilities I needed to keep her in line. As soon as we entering a battle to keep her focus on the target not going to attack another near-by group.
The point is that i found myself managing and controlling my apprentice in a more detailed manner, and my game world just opened up.. I never was the type to manage companions in MMO's before but in this case it really fun.
Do you control your companions or let them run next to you do what ever things they do?
