FF14 literally stated that ARR 1.0 failed do to problems with cloud servers, as cloud servers were popularized in japan by PSO and PSU.
Also Guild wars 2 has some of the worst servers possible. WvW has been complaining about servers since launch.
In fact players have been complaining about increase in input delay to server reation since 2017 when AWS was added to GW2.
There are so many skills going off damage numbers and skill animations aren't synced and lag several seconds behind. Its been like that since launch and it will never change.
GW2 says it has low ping, which server to player ping is low, but player to server ping is extremely latent. This is some strings from them.
As you will see ever since AWS has taken over peope living literally next to the servers are only running at 70% of what they used to ping wise. Literally GW2 lost half its player base when the servers merged to AWS.
