Yay! Well its been 2 days.. I hope its in on next Tuesday's patch, if not sooner /pleads So want to level my other crafters, but as much as I like crafting, I am NOT a sadist, so I will have to wait.
The fix is now on Test, and is properly displaying bonuses in the tradeskill xp bar. (Tested with Twiddy's Sculpting Hammer) Thank you!
So do we believe Bunji about the Mark of the Far Seas [please say yes, please say yes]? "TRADESKILLS Mark of the Far Seas will now correctly modify tradeskill experience gained."
Oooh I hope so! And hooray! Corrected an issue that caused daily and weekly tradeskill missions in Altar of Malice to grant less experience then intended.
That specific item will be fixed in tomorrow's patch (the experience bonus was moved onto an effect on the item rather than on the base item itself); the other items mentioned in the OP will still be broken until my more generalized fix goes in.
