@Riot, regarding Athene's Unholy Grail in 4.10
Why did you go so far to nerf this item into the ground? Couldn't you have simply increased the overall build-cost?
Did you ever consider the consequences for mana-hungry champions like Cassiopeia who entirely depend on mana-regeneration and what this kind of change means to them? You even went as far to cut down the magic resistence, can you imagine how this cripples any squishy midlaner?
You're badly hurting traditional mages who already lack any mobility and thus heavily rely on a constant use of their abilities to zone their opponents or just to keep up with farming.
If you're seriously worried about champions like Nidalee who seem to exploit this item for constant harassment at zero risk, you should restrict your dislike to said champions without destroying an item which is being used by far lesser 'evils'.
I haven't seen any compensation for champions (besides Galio) who consider it as a core-item in ther build, how are you going to deal with this issue? Are you simply going to tell them to build a Tear of the Goddess? What use is Athene's Unholy Grail even anymore if it fails to fullfill its role as the the number one mana-regeneration item?
