I have her at level 57, 6 stars, gear level VI, with 5/6 towards VII, so I'll have her purple tomorrow. Her abilities are 3, 4, 1, 3. Her power is 3596, and her HP is 8.9k
I dig her abilities a lot, she is like a swiss army knife, does a lot of everything. Maxed out, she can call for assists with 50% more damage (jedi), counter with +50% damage, stun on critical hits, self heal on a hard hitting special, and if she is leader she heals any jedi (all jedi add 40% tenacity, and gain 5% of health whenever they resist).
I want to try her out as a leader on a jedi team, but I need to upgrade her ability there, she could be the anti-sith leader. When Vader and Sidious start laying down DoTs, ability blocks and healing immunity, they will just be healing the jedi on the other team.
A geared up 4* Secura would probably still be quite powerful, as she brings a ton to the table if you upgrade all of her abilities too. Don't remember what her HP was at 4*, but it's one of the highest on my team. Really hope she becomes farmable in the next update!
