Blizzard, we need to have a talk about how much of a liar you are when you say "heroes never die"...

This is a hero never dying. For context, this is a tank character in Paladins whose ultimate makes him and anyone on his team within a short radius completely invulnerable, and he used the ult in from of three people to keep a last-second push alive. An important thing to note is that in this early build of the game, his shield had a very long cooldown (judging from the video, I think it was around 18-20 seconds) so he was guaranteed to die if he didn't ult or charge away from the payload.

I honestly think this exact functionality would make a much better ultimate for Mercy. Instead of staying behind the team to flee and leaving your team to die, the Mercy player can fly to a target in trouble and keep them in the fight guaranteed for a short while. The main thing that would balance this is Mercy being locked in place for its duration (unlike all other support ults), so you still have a need to plan an escape if things don't work out and it requires holding a position in a way that other ults could exploit if timed properly (throwing a Zarya ult into it to set up a combo after Mercy is done).
