I experience similar problems too on the 3 EU pve servers I play on(EL 1013, Siptah 6455, EL 1046).
Just trying to log in to an official server can be problematic because ping is often in the range of 200-400, however it seems to settle below 100 after a few tries.
- Thralls and npc sometimes do not react and just stay there like statues for some time.
- Pathing of followers and also npc’s is sometimes weird where they run in unexpected direction.
- followers on defend me deciding to put away their weapons and only fist fight.
- Followers deciding to just stand still and take a beating without fighting back or even draw a weapon for a long time.
- npc’s sometimes teleporting around.
- Followers and objects can be hard to place, it may be more of a problem in high altitudes, but it definitely also happens in low places.
- Stuttering and sometimes freezing for several seconds and when it becomes responsive again I am far from where I was initially.
From my experience it is not just a Age of War thing although it got quite a lot worse, but it escalated right from Age of Sorcery.
I think some of the problems can be a problem in the game code, but also servers seems to make problems worse, testing in singleplayer or on a good clean private server then most of the problems are much less serious but can still happen
