...and chalice unique passive applies to all of your mp5, which means the mp5 would beat out AA's mp5 earlier as you drain mana.
Like I said in my original post, there are champions with high costs and a low pool. Champs like these will need BOTH AA and GRAIL. (Kog's ult can cost up to 400 mana per cast with a .85 second CD)
sion roughly have 7.5 mana regen at level 3. Whit Chalice it's 15. At 0 mana its 30 per 5, so 6 per second. In 58 seconds at 0 mana you get 350 mana tear has and well, in the same time tear grants you 87 mana not taking into account base mana regen, so Chalice need 14.5 extra seconds at 0 mana to grant equal mana than tear. So in the first 72 seconds, either spamming or not, either whit 0 mana or not, Tear is better sustain and not taking into account the Mana from the passive. Also, having large mana pool means you can chain better you'r skills. Or you want to tell me that AP Trist (or even AD but she don't build mana) benefit more from having more PASSIVE mana regen, than having the possibility to chain her skills at least twice?
Want to talk? Use numbers. Math. Don't talk bul**** whitout proof, because my numbers say that Tear is better at least during the first minutes of the match. And late game, it's still better on low pool champions, like Sion, Trist, Miss Fortune, Karthus, Kog Maw, Anivia... etc etc.
