Does this healing buff also work for: Fountain Regen? Do you regen 25% faster than your allies? Lifesteal? Does this really buff all lifesteal by 25%? how is this not an adc off-meta choice? Revives? If GA pops, will you respawn with 25% more health than normal? If you have any other weird nuances, I'd like to know. Thanks.
All incoming healing. So ifs in the regen/heal category. It applies.
GA is not a regen/heal.
As for it not being an ADC item, there is no stage in the game that it would be worth building. You could MAYBE do it as a 6th item, but it would only be effective in drawn out fights, in most cases ADCs get bursted or not and thus wont make use of the heal bonus when GA/Maw Shield are going to provide instant value.
ADC doesn't build it because it's simply not optimal for them. It increases healing by 25%, which means Bloodthirster would give 25% lifesteal instead of 20% lifesteal. Thing is, that 5% healing is 50 hp when you are doing 1k damage. You could also buy another item to increase your total damage and boost your damage so that you get that 50 hp back anyway AND kill the Rengar that's flying at your face trying to deal damn near true damage AD.
