Whirlwind attack?

This is something that has annoyed me for a while,
The Whirlwind attack icon from the [ skills] (as shown here[whirlwind attack])
Is different than mine and the wikis. http://guildwars.wikia.com/wiki/Whirlwind_Attack
Are there two symbols or is the icon on [skill ] wrong?

Um straight from the site:

"This skill was released with a different icon, which was replaced in a later update. The rationale behind this change is unknown."

The one you showed is the old one, if you read the whole wiki. The one on the top of the page is the new one.

Gah, sorry. Plz close
