Thank god someone finally posted in regards to "Effective Health". Its incredibly important knowledge that every MOBA player should understand as it allows you to make much more informed decisions during the mid game as to what you need to itemize towards.

In my opinion LW should be a mandatory 3rd item on ANY physical damage carry build and BotRK should be added somewhere as well, but only if your Vayne/Trist/Kog considering most of the other AD's gain significantly less out of an early Blade then these 3. Needless to say that if the enemy eam has 2 targets over 3k HP it should be purchased. BotRK is a very underrated but overrated item at the same time due to misconceptions surrounding its given AD and passive.
