I'm...done giving money to this company. I suspected this game would just piss me off over and over again >_>. nerfnerfnerfnerf ad infinitum.
It's not a Nashor's nerf. It's Fiendish Codex getting a different recipe that doesn't involve mana regen anymore. If Fiendish Codex is now cheaper to make in total (we only see the recipe cost there), then Nashor's Tooth has actually been buffed because its recipe cost was lowered. I can't think of anyone that builds Nashor's that wants mana regen so badly, anyway.
AP Yi got removed from the game. -100 base HP regen, -2.8 AP ratio on Meditate.
Giant's Belt got a small nerf, but interestingly the items that build from it seem unaffected.
