Players move at less than half speed most of the time.

As I play GW2 (PS4) in solo multiplayer games and in the backyard, my players are walking at less than half speed most of the time. I can see how fast they walk or run for a few seconds at a time and the...its like being stuck in quick sand.

I am not playing in true multiplayer, so I know it isn't a connection lag issue.

Any help or suggestions?
