I could never play Tira. Like I need to learn how to switch from Jolly to Gloomy or Gloomy to Jolly. I mainly use everyone. But Tira is my least favorite.
Yes, Ivy takes practice and effort, because you have to learn how to change in the different stances (SW-Sword CL-Coil Wp-Whip). But check her out, she worth playing... to me at least.
