ELI5: How are the current dungeons hard?

[Jinglypockets]

The most obnoxious thing about the netcode is that the game calculates and assigns how much damage you're going to take from a hit before that damage is actually applied -- usually about 0.5s before the damage actually takes effect, so the timeline looks like:

00:00.0: Boss starts casting Raidwide with a 4-second cast time.
00:03.5: You get assigned 10,000 damage from Raidwide.
00:03.6: You receive an absorb shield for 10,000 health.
00:04.0: Boss finishes casting Raidwide.
00:05.0: You receive 10,000 damage. 0 of the damage is absorbed by the shield, and you still have that shield despite it being applied before you took any damage.

Any mitigation you try to use for a big hit has to be applied *before* that damage gets calculated and assigned, otherwise it does literally nothing.

Which is why my Spreadlo frequently gets wasted if I'm just barely too slow with it, and things like Tank immunities have to be applied well in advance of tankbusters if you want them to actually work.
