Starkiller and Satele

if you invested into SS without other OR that seems a waste compared to other tank options for him. as for the aoe buff dispel that works more so for taking stranger on offense to try and kill something like Rey to keep the crit defense down. now you could throw in as said above Mace Windu as a tank. GK is a better option for the crit hit immunity keeps marked maul around longer. He has the debuff dispel that gives you the opposite and feeds himself tm. he has a call ally to assist which has no real downside. If it is stranger works around his kit quicker, if it is Maul gives bleed out. Starkiller starts to stack for his stacks. Old ben is one i would rather take for stranger as when he dies, he feeds offense up 50%hp/prot recover and 25% tm. has a taunt that also gives defense up helping with aoe dmg. has a aoe AB and removes TM. Juh has selfheal and a stun built in granted better int w with Omi. Plo Koon offers more dispel since every time he basics it will dispel all buffs and feed him defense up for removing any effect. 
if you invested in SS without having other OR Jedi/ working on them that is a waste for her to sit on stranger and do not a ton compared to putting mats to a gl/conquest unit. 
"In addition, her legendary defiance Omicron about “equalizing health with the strongest enemy while below 20% Health” doesn’t seem to be restricted to all OR teams, meaning a Satele boosted by Starkiller’s 100% Health and Protection stats will still equalize, making her quite possibly the best non-GL Jedi Tank to use in the team..... Once again, my point it is tied to all OR anything under a restriction including Omi is tied to that requirement, so she just lets a jango or full or SS go around her anyways and does not do anything to equalize. if you understood half as much as you like to put out you would remember it was nerfed at release of her because it broke Rey.
