Soraka and sight stone. Convince me !
So I pay for 400g of health but since I plan to use my regen/starcall/potions properly, I plan to use about 15 heals per back. Which will cost me 150% of that health. So at the end of the day, the sightstone worth -200g of stats because it hinder my regeneration more then it help.
Another way to look at this. Each time I heal with the sightstone, it cost me 15HP. which is about 3.5g worth of potion. Not much but it stack up each time I cast heal until the end of the game.
Don't get mad at me, I know the wards cost more money still and eventualy it will worth it. But where on a normal support it's a 10 mnutes investment, on Soraka it takes up to 25 minutes before you break EVEN with the sightstone.
Comparatively, if I buy a blasting wand now, I'll produce about 5.5gp worth in HP everytime i'll heal and about 6gp each time i'll hit starcall. Assuming I use perfectly the 3 wards it would take about 6 backs to compensate that. And this still disregard the eclipse, wish and starcall damage (and I'm not saying a blasting wand is even a decent choice on soraka) . It would take the entire game length just to break even. At this point, the sightstone is not even slot efficient anymore...
tl;dr : The extra hp on the sightstone make soraka pay more for each heal she do. It will take 40 minutes of game before she START to see the benefit from the sightstone.
Am I missing something, Can't I just buy wards when needed instead ? Better yet... couldn't her teamates who saves a ton of gold in potions could buy a few wards once in a while with that extra gold ?
