From SEA servers. Playing on PC.
I am immortal. It seems everything seems to have a severe slowdown, or screen freeze for 1 second but no crash, and long loading time for certain instance zones such as entering the vault as vault defender, entering the immortal hall, and frequent 1s screen freeze on overworld farming.
This never happened to me last time. Only starting to experience this when my clan become Immortal in this week Monday.
Also, I am not alone with this. Even my clan experienced the same slowdown and loading time for certain instances.
