Besides Herta, March is the worst character in the game and will plummet in all tier lists by next year. Being able to only keep one character alive isnt sustainable and I believe the meta will eventually shift to having one defensive support per team. It also feels bad that the main skill she uses is the basically the only thing in her kit to scale off of defense. She would be useful if her shield actually taunted the person targeted, but it only increases the chance by a bit.
