Will there be better information of player death in poe 2?

It's not a strain on the servers. We would keep that information client side if we were doing it.

It's just that it's a complicated UX task with a lot of considerations, and a lot of tricky details. We could get 90% of the way there very easily. And the last 10% of making it correct/useful would require way way more work.

We don't currently have attribution to specific skills at all. It would be easy to say "Fire damage killed you". It would be easy to say "The boss killed you". Harder to say "This corpse explosion skill did X damage to you", and much much harder to say "This debuff resulted in Y extra damage to you".

If it's not accurate, then it's kind of useless. So we would have to get this stuff right.

And to be completely honest, I just don't value it as much as other improvements we could make to UX. It's not like it's off the table. But there is a lot of other UX improvements that would come first before implementing such a screen.
