New Banshee's Veil
Is it also a possibility that 
looks a bit weaker because it is "the" anti-mage item (MR + shield + Build path), and there are a lot of (unexperienced) mage players right now and people are building it a lot to deal with them, making Banshee shield look quite a lot weaker than it actually is because a lot of magic spells procs the shield so often. Also with more neutral objetives competion (Blue and Red buff icon on minimap, new Herald nad Dragons buffs) there are more team fights in less time and this happens often in every game resulting the 40s not enough time to refresh the shield (if you received any attack the count of the shield back to 40s) Maybe reduce the 40s of cd in the shield to something near to 30s could help it. Right now the price and stats are not gold efficient..
Previous Banshee's (pre 6.9)
Cost Analysis
> Gold Value > 70 magic resistance = 1260 Gold > 500 health = 1333.33 Gold > 100% base health regeneration = 300 Gold > Total Gold Value = 2893.33 Gold
Gold Efficiency
: is 99.77% gold efficient.
The passive must be at least 7 Gold for to be gold efficient.
Actual Banshee's (in 6.9)
Cost Analysis
> Gold Value > 70 magic resistance = 1260 Gold > 300 health = 800 Gold > 100% base health regeneration = 300 Gold > Total Gold Value = 2360 Gold
Gold Efficiency
: is 96.32% gold efficient.
The passive must be at least 90 Gold for to be gold efficient.
So Riot now offers now a weaker version of Banshee's and increases the amount of mages in the rift so why don't keep the previous Gold Efficient amount?
This could be reducing the cd from 40s to 30s or adding extra 5MR (5MR = 90g).
What are your thoughts?
