You are either dead or they are dead way before you can really take advantage of the mana. Once again I believe there are many other more efficient ways to offset mana problems such as runes, masteries, smart play, Clarity, Ancient Golem buff, etc.
This is the case for me whether I'm playing Kassadin, Karthus, or Anivia. Although mana is a great stat to have on the side, I would never personally itemize for it with the current state of item balance.
Personally for me the mana bank Archangel Staff provides is good and all, but maximum capacity is kinda overkill, especially with the 25 MP5 it gives. Its main selling point for me is the AP it can provide, since I'm not a fan of win-more items like Mejai's. Ultimately Archangel is an item of longevity for casters when Golem buff isn't available isn't it, assuming you don't get focused for some reason?
Anyways, thanks for your 2 cents statikk
If and when I get up to high elo, I'm unsure if my views on Anivia+Archangel will change though =/
