She is one of the slowest character without any slow and with only one speed buff on her passive at level 5… a possible push back at level 4 but useless if she chase you. And a stun only at level 10.
All character have at least a control (Slow, Stun, Push Back or Bump) or a movement skill (dash, jump, stealth, speed boost etc…).
So everyone should be able to run away from her as she is the less mobile character with Reyna and Ghalt. If you are in a middle of a fight that you may not win without any escape plan, it’s your fault
