What do you think was the worst thing this game experienced from 2.0 until now?

Back in 2013, before they fixed the latency issues in Titan HM and you had to do it for the relic, that was when FFXIV was at it's worst .
Tumults, in the center, you move out, but the game didn't think so, you insta-die. Landslides? Move out, still get hit, another instadeath.
I found it particularly bad, as the latency issues combined with my NZ latency was the worst.
The toxicity was at an all time high, directed at anyone that got knocked off. I often got knocked off with landslide even if I moved before the telegram appeared on the ground, it was the first and only time I was told "it's not latency, you're just bad" and "uninstall the game and kill yourself" lol. The only time I ragequit the game also (my poor chocobo doesn't have the starlight barding because of it).

When they fixed the issues, I cleared it like a breeze, the game got good again :P But those were some dark days.

Eureka is nothing compared to ultra-latency titan relic trial.
