Guild Wars 2

Zephyr’s Speed.
Move 25% faster while attuned to air.

Versus.

Time Marches On
You move 25% faster. The duration of incoming movement-impairing conditions is reduced by 25%.

I don’t know what to say. I know we can’t compare oranges with apples, but aren’t they still traits? The power creep seems alarming.

Geomancers training exists to cover the -33%impairing conditions. Plus eles have a 25% movement speed signet while mesmers do not. Finally, elementalists have many more sources of swiftness through traits and skills than mesmers ever have.
