I think her beams mechanic in reverse could of been interesting. Healing for more the lower their health currently is. But yeah that beam would be almost like Moira’s left click but worse. Short ranged heals are rarely a good thing, especially from a flying hero.
I just thought it was odd that Echo had no shields at all. She just looked like a hero who would make use of shields. A very thing and fragile looking body, heck parts of her aren’t even connected just floating free. Yet some how she’s a full 200hp hero while zen only has 50hp and then shields.
Very odd lore wise imo. Though I think game balance she’d be a bit strong as a DPS if she had personal shields.
