The Vah Shir Language

[Hottbiscuits Dreadmuffin]

Patch notes:

Thursday, September 16th 2010
Haynar: Vah Shir language should no longer be trainable.

Sunday, April 17th 2011
Kanras: Vah Shir language no longer available at guildmasters.

Questions:

1) When the Vah Shir language skill was removed, did people who trained in the language have it removed from their skill set list?

2) If those who trained in the Vah Shir language did not have the skill removed when it was removed as trainable skill, are they still able to share the language with others?
