Of course, factoring in 250 gold for the hp bonus,

the sightstone pays off after 6 wards, like everyone else said,

2 wards placed at a time means 2 wards per 3 minutes =

pays off after 6 minutes, 1 b somewhere after the first around of placing or so, and another 3 minutes. The b is important to get more than 4 charges.

Being generous, if It took 1 minute to b and you b'd at the right time, it would pay off after 10 minutes.

Now for ruby. assuming 300 hp is worth the 250 gold plus 475 for the ruby crystal,

1400 - 725 = 675 gold to pay off.

Asssuming you placed 6 wards with the normal sightstone:

6 x 75 = 450

675 - 450 = 225

225 / 75 = 3 wards

so ruby sightstone pays off after 3 minutes.

being generous, rushing sightstone, you could pay off ruby by end of laning phase,

and as a support you'd be saving a spot for wards anyways.

so you get inf+ wards, pays off after 6/9 instead of sightstoneless, repositionability, and the fact that you get 250/725 gold's worth of hp.

Whats not to like? It pays off for itself, it give hp instead of a normal slot, and realistically the ruby sightstone actually allows more wards per b (6 charges as opposed to stacks of 5, plus hp)

Realistically, S3 is a great time to be support with cool actives, increased gold to get

them, and the even the fact that shard of true ice even includes gp/10

TL;DR

ANY SUPPORT WILL SAVE A SLOT FOR WARDS, BUT NOW IT PAYS OFF AND YOU GET 300 HP BACK AS WELL
