User blog comment:Leyrann/Why Chalice of Harmony is OP/@comment-4881935-20120828070433

u know what, i'm just going to show you a little bit of math to show u how bias ur view is.

the highest base mana regen is 8. At level 4 (a common time when chalice will get brought), the mana regen is aroud 10.5. With Chalice, u gain 7.5 mana regen. Notice that chalice only gives u a 0.5 mana regen boost from meki pendant. So, in total, you have 18 mana regen.

now, you range around 18-36 of mana regen. Let's also not forget, at level 4, the common mana pool at his time is only around 400. Going anything below 150 mana is extremely risking for any champion because now that leads to the possibility of them not being able to cast a spell due to mana restrains for a small skirmish. So that means right there you won't be going below 40% of your maximum mana, so now the total range that you actually get is around 18-28. Also, the more mana you actually have, the less regain you actually get, so even hovering at the risky area, you won't always have that high amount. So ideally, you will probably only get that 24 per 5. Look how impressive that 6 additional mana regen is.

If you really look at Chalice, you will notice that you don't gain a lot of huge benefits early game from it. Until in the mid game will Chalice will start to pick up because then champions will have more mana and mana regen, which at that point, Chalice is really not needed as much because you have more mana and mana regen.
