I've solo'd the HRancor with several different compositions now, and my FO squad does it with the least amount of manual effort, time, and stress.
I'm ready to unlock CLS next time it rolls around with the gear and mats to take him right to at least G11, 2 zeta (IBAT + Learn Control).
My question is what is really needed to pull off the one-man Solo? Speed target and gear target mostly.
I have a full set of crit damage and crit chance mods ready to go on him that will grant +85 speed but not sure it's enough. +Offense on cross, +CD on triangle, too.
