My feedback as once starry eyed and now disillusioned player

[Jeeqbit]

I was running the newer dungeons on my main as a 740 Viper. 3 times I wasn't in any of the line of fire mechanics and was killed all three times. Even the other players saw me out of the target zones.

Irrelevant. Cast time/red area is all that matters. If you are in the line of fire when the cast completes, then subsequently run out of the way, it will still hit or kill you when the effect/animation is processed. We call this snapshotting.

So:

1. Cast completes while you are in hit area.
2. You run out while game processes animation and cycles through players to apply damage and sends out the hit/dead packets to clients.
3. You see yourself die suddenly despite being out of hit area.

If it doesn't obey these rules then you have some packet loss or an inefficient route - this can often be improved with a VPN.
