Hi. Lifeweaver doesn’t have two different voice lines to his ultimate at Brazilian Portuguese Language. For some reason Lifeweaver says “A vida protege a vida” (Lifes protects life) if he’s your ally or your enemy, doesn’t matter. Why? I don’t know, sounds like a bug to me. 'Cause every other heroe have two different voice lines.
(Yeah, I know this is EN forum, but Blizzard Support directed me to here)
