ADC itemzation is broken (op)
well pretty much All AD itemization in but lets focus on adc for the moment
ADC can build full damage, while getting absurd suitability
30% burst damage reduction
12% damage reduction vs specific target
then you have life steal items
which include
again
but also
to bring down the few tanks you cant burst down...
to give you a freaking shield in cause you wanted it
if you want crazy cdr and mana you got 
if you want aoe you got 
evemy team has armor

then you have
and tell me... do u need to ever sacrfifice ANY damage for these items? NO, you get survability but in at no extra cost into nearly every freaking item
and the items you dont have survability on
consits of pro the most broke item trio on the game
what does a mage get for survability while still going offensive?
for armor and passive is once every 1:30.. and we cant do anything while in it other than hope our team helps
oh great. i get
passive, this works great vs those big ap threats like...umm.. like... gimme a sec, i'll get back to you when a find a big ap threat... oh
because she can murder you from an entire screen away without ever needing to get near you
oh but we can get hp on our items
right
cost gated by active
cost gated by active
gated time to stack,
gated time to stack
YAY AN ITEM NOT GATED BY A PASSIVE THAT ONLY CERTAIN CHAMPS CAN USE!!
NOPE!! instead of adding an internal cooldown to prevent abusers from turning a 1 second slow into a permanent slow they got the stats
so cost inefficient unless you where one fo the champs than can still turn it into a perm slow
this is easily the best item for hp and ap, as it least PART of its passive can always be used.. but even the other half is gated by cc
so champs with no form of cc still have no item. (and yes, you all know im talking about
)
THERE IS NO "wait to stack" unless you get
first item.. the game has about an 80% chance of ending before it fully stacks
at least you can get early and then stack while you get other items
