Why and when did Tear of the goddess lose its mana stacking.

The passive 1 mana/4 seconds. Where did that go I don't see it in the descriptions and I haven't seen it on the item it self looking at the mana by passing my mouse over the item to check its stacking. I havnet seen it moved form any patch notes. While mages don't really need the item for not that any one builds the items any more. I love to build it on my fighters for but its already super hard to stack and the loss of surviability form having to build it early hurts especially when you cant get any offensive stats with until pick axe which is a back on its own and it has no defensive stats lost its mp/5. Hope your enemy doesnt notice that you didnt buy defense or offense on your first back and you get zoned even if you were winning before the back makeing it even harder farm and to build. In the end while mages get more ap than on a normal ap item for building a fully stacked (most ap for a single item if rabadons doesnt have any other items in yet). fighters get by with just barely 3 more ad on for stacking it if not 3 -5 less ad. does have a damage passive but why should its passive be required to keep up with the ap of with out even factoring seraphs active.
