I learned just recently that the white tiger was a charity mount. Having read about the Charity Christmoose mount, I do realize that those mounts will never be available again.
But ....
The white tiger is one of the coolest mounts, EVER. Perhaps if you had another charity ... or ... re-released the White Tiger mount for a limited time as a special occasion or another....
Would you consider doing this? I know it is my fault for not having played during the time the white tiger was out, I will painfully understand if I lost it forever.
