This article completely fails to mention that Yamatos buffed ult came in exchange for it NOT making her invincible anymore, and instead claims that it still does that.
You can literally just kill her even if she ults now.
The new buffs included 60% damage resist, which the nerf dropped to 50%, along with shortening it slightly.
At least part of why she's so strong right now, is that people don't know that she can be killed, so they don't try.
