New ADC's changes and how everyone reacting to how this "buffs adc's" is not 100% correct.

Alright now on the PBE it states as follows Infinity Edge cost 3700 gold and instead of getting crit chance and 50% increase in crit damage it now doubles crit chancec and makes 20% of your crit damage true damage(still taking the same amount from a regular crit not a 50% increased damage crit but 20% can't be defend agasint).
Zeal items by 200 gold and zeal increased by 100. Not the bigggest thing in the world but still isn't as cheap as it used to be. Now let says you get the new item as well. Whicih will cost you 3400 and LW got its priced increased by 200 as well. First thing with this change you wouldn't be building I.E first since you wouldn't get any of the benefits till you had atleast 1 zeal item completed So expect something like Zeal item >Boots> I.E > LW > New Item or essence(depending on what you need, cdr with reduce ult cd or attack speed with ad) > Zeal Item ? Which will cost you about 15,500 which is to reach this new "buff to the adc" for the attack speed crit builders and you Need that 100% crit plus a bit more ad that the new item gives or Essence Reaver to reach what they do or bit more then they do now and if the enemy team is smart they would be building armor to make sure you have to get LW cause to relay on 100% crit when still exist to melt through tanks with that 20% reduced crit damage and hope that 20% true damage is enough is probably not gonna cut it since adc's usually have to deal with the tanks first since they are trying to get to you while the other adc or mid laner is in the back. So, It's most likely 60% crit with 20% of it being true damage + the 35% of total Armor pin if they go Lord Dominik’s Regards and 25% if they go Mortal Reminder and remember they removed the Gaint Slayer Passive and the item itself. So they have to atleast get 12,100 worth of items to have 100% crit and to start dealing the damage they once did, or 12,700 if they get essence, New item, or maybe BT. So this pretty late game to be at unless you hand fed the adc.

Now on casters they have pretty much an easier Build path since they can take the new item + a zeal item or essence Reaver and be set. Jhin would bennfit from the new item since attack speed increase his MS when he crits and his AD and would alow him to have an early power spike till the tank builds since his passive already Reduces his Crit damage by 25% and this would lower it by additonal 20% and I can see Lucian and MF benfiting from this change as well but not sure how much.

which at this point I would think it would be better to get top or mid rolling first since they have much better early game then the adc's now with this change and mid game and worry about your adc and enemy adc late game.
