ELI5: How are the current dungeons hard?

[Caitamm]

Yes, and then you eat a vuln stack because for the server you are not in the same spot. Is it doable? Yes. But it's annoying as hell, and it stems not from the fight design but from how the client and server interact. A lot of other MMORPGs don't have that issue.

I've....never had that happen? Are you sure you're not getting hit by the side/frontal cones that sometimes overlap the mechanic and are misattributing it to the X/Os?
