A suggestion to fix the unique passive "Eternity"
for those that dont know, here is what Eternity does:
> 15% of damage taken from champions is gained as mana. Spending mana restores 20% of mana spent as health, up to 25 per cast (toggle spells heal for up to 25 per second).
no one really cares for this passive. you need to take damage in order to get the mana regen effect and the health restoration effect is pretty bad unless you spam abilities ALOT. my suggestion is to change it to be more in line with 
or 
for AP champions. Here is what i suggest the passive be changed to.
>Reduce damage taken equal to 5% of your max mana and gain mana equal to 15% of the post mitigation damage taken. Magical abilities that cost mana heal for 20% of the dmg dealt.
This is JUST an example. my main thought is to just turn the eternity passive into an alternate AP version of DD or PD. having to take damage in order to gain mana is just flat out horrible without some kind of sustain or dng mitigation to justify that.
's version of the eternity passive stays as is
and maybe even 
getting out of hand
which is a item that is fairly offensive more so than defensive. also, its still very bad even if you area tank. you are not going to go out of your way to get intentionally poked down by someone just to regain your mana. its just a really bad passive in general. amu is probably the only champ that goes OOM significantly enough in fights to benefit from it.
so much) . it was spell vamp was reworked into 
Effect, but for some reason only known to God Riot decided to get rid of all healing effects from mage items EXCEPT gunblade, which is a hybrid item, and give them to ADs intead... as ADCs dont benefit enough from LS stacking.
