I doubt it will run 100% while you sleep. SWTORS code is supposedly a nightmare and getting anything to perfectly work is a near impossibility. Look around the forums and decide for yourself if you wish to buy it.
If your ONLY interested in a 100% afk, then its not right for you. But if you want a bot that can run on its own with some minor assistance here and there, its great.
Well normaly i wouldn't be bothered with minor assistance, have had my fair share of problems with honorbuddy, but i use honorbuddy when im awake as i hate leveling and making gold, i only do raids and stuff in wow, but i actually like playing SWTOR by hand, i just think the leveling is slow and wanted the unfair advantage through the night for a boost. and i cant assist the bot while im asleep
Eaven in Honorbuddy you can't leave bot 100% alone while leveling, buddy wing now has problem since 1.5 was realesed and now its faster to run by self, until devs give us new realese.
