Guild Wars 2

The skill specifically states “50% movement speed increase”.

The wiki states “Effects that increase movement speed do not stack with each other — only the greatest effect takes precedence. For example, a character under the effect of Signet of Air (25%) and swiftness (33%) will only move 33% faster. Maximum out-of-combat movement speed is capped at 133% of base speed; maximum in-combat speed is capped at 125% of base.”

Does Signet of the Wild cap out, like everything else, at 33%? Or is it the only skill that exceeds 33%?

Afaik it will give you 133% when out of combat and 125% when in combat much like super speed on engineers and eles.

My guess on what’s happening is that being larger gives your character a longer stride, and therefore a higher base speed compared to a regular-sized character. Or, it could be one of several cases that are an exception to the rule, such as the elementalist’s One with Air trait that grants superspeed. Just guesses unfortunately, I’m not in a position to mess around with the signet at the moment.
