I think Lady Locke is heavily underrated!
With emblems and high level troops, I have raided against her with 1,330 DoT before! That is 1,330 damage TO 3 ENEMIES over 4 turns. That is nearly 4,000 damage over 4 turns. 1,000/turn basically. There are very few heroes who can do that much damage over time. Plus, she clears all ailments!
I know her special is dispellable, but so are so many other specials out there. People don’t dismiss GV people his burn is dispellable. Maybe against some teams, they can take her out easily because they have a cleanser. But many teams don’t. I don’t have a cleanser on my team, if it wasn’t for Hansel, she would destroy my team!
