Let's Talk Leia

I face a lot of gear 9+ Leia's with omega on her stealth ability. Mine is only 4* so I don't use her. Only a very few characters can possibly go before her due to her speed. She starts off with stealth, and spends the whole match hiding behind tanks. When her stealth ends, it has already cooled down, so she immediately stealths again. So a tanky team can extend the match, giving her many, many turns doing 10k-18k damage per round (that's what I'm seeing) except on turns where she uses the stealth ability, and you can't target her until she's the last person standing. She also can't be counter-attacked while stealthed. She's very glassy, but the permanent stealth effectively gives her as many hit points as all your tanks combined, and her damage is second only to Rey. She's by *far* the most dangerous character on the whale teams I face. RG, Sun Fac, Rex, etc., are all good, but Leia is the only one that makes me think hard about how I'm going to attack that team.
