I could have swore I just read a red post about how high CD reduction items like BFT and Nashors need the MP5 because of the spamability of spells you get with that reduction.

Now it's being removed?

I think Xypherous mentioned this in passing during one of his posts. I think the idea was to give AP champions that don't necessarily want MP5 an early option for CDR and AP.

id say its so AP champions have to actually spec reasonably hard into mana regen if they want skill sustain, this also means that certain weaknesses are more accentuated, making champions more obviously mana hungry so they have to choose between specing some mana regen, mana or continuing building bulk AP.

Actually it's more because there is already a Codex option for mana-hungry champions, and codex doesn't need the MP5 restriction anymore (since the champions are more balanced).

So you can now pick chalice for MP5, and evolve it into AUG (with codex). Pick codex for CDR and evolve it into Tooth. Or pick Codex for AP/CDR and evolve it into Morellonomicon...

I am apalled that mages are the target of branch-wide nerfing.

AGAIN.

they're ninja nerfs, the easier to fix... Also the chnge to MP5 isn't a nerf since the price of those items drops

So... err... did they actually drop the gold cost of every item they axed mana regen from...?
