FORGE GUARD mastery bug

The second mastery bonus of FORGE GUARD , the Stalwart buff, now gives 5% increased armor for each hit you have taken in the last 10 seconds, up to 10 stacks (previously 3%, no stack limit) instead of " The second mastery bonus, the Stalwart buff, now gives 10% increased armor for each hit you have taken in the last 10 seconds, up to 10 stacks (previously 3%, no stack limit)"

Please fix this fast! I play on HC!!!
Thanks!
