I think Teebo's leadership is best used as a misdirect. Currently, with the exception of Nute Gunray and Teebo, stealth only prevents attack which means if everyone goes stealth there is no benefit. That said, for now, I wouldn't level his leader ability beyond lvl. 4. I think a lot of people see this as a way to safely use low HP units but this is not reliable. I think it's better to use Teebo's lead as an anti-focus ability for longevity. I'm still trying to crack the code on that but here are my notes if anyone cares to decipher them:
- TMR, Stun, Slow // Roy Guar, Daka, Fives, Cpt. Phasma, Yoda, Magma T., MagnaGuard
- Heal Attack // Ahsoka Tano, Jed Con, Darth Sid, Talia, Mace Windu
- Self-Heal Tanks // Mace Windu, Finn, J.K.G.?, C.W. Chewbacca
- Counter Tanks // F.O. Stormtrooper, Fives, MagnaGuard
- Counter // Aayla, Kit, Dooku ???
- Resurrect // Old Daka, Ewok Elder
- Healers // Barriss, Luminara, Jed Con
- Revives // HK-47, Boba Fett
- No long tuants! Kylo, Savage, Old Ben,
Vader? Nute, Anakin???
There are 2 or three teams somewhere in there that excel with Teebo as leader.
