I haven't experienced this feature but I don't love the idea of AFK people being ported in. It doesn't sound like there's any point to the timer, if you just have the prompt stay up then couldn't the AFK person just click it when they get back? And then they'd port in alive instead of being dead and had multiple people waste MP on trying to raise an AFK person already.

I don't think we need to encourage people to pull early and ignore everyone else in the run. It seems like the opposite of the ready check and countdown timer features that seem to get used less and less, now you can just go and don't have to worry if people are ready because they're coming anyway and then it's their fault if they die.
