Hi guys, I digned 90 on my mage this weekend and, for the sake of it, I did the old lfr, T14, I might have been lucky but ... on every single boss, i used a greater charm, and on every single one i got a gear from it, is it, for the t14, 100% drop rate ?... if so, it is a pretty good way to get sha cristal pretty damn fast... oo!
I don't think it's 100%, but it sure is very high - I'd put it around 80-90% from personal experience. Pretty sure I've had some kills with no bonus loot every now and then.
As for sha crystals...after timeless isle gear spam, I'm swimming in them.
