@Riot: Ruby Sightstone. What's being done with it? Will it simply be left as a lackluster item?

With Greater Stealth Totem being so much more cost-efficient than upgrading to Ruby Sightstone, it's clear that the only reason one would upgrade to RSS is if they are dealing with a 100-0 assassin like Talon and need 250 extra health to survive. Otherwise it's simply better to get GST, which is MUCH cheaper and pays for itself after 3 wards, whereas RSS takes much more.

I would certainly love to see RSS get more on it than just 250 extra health compared to regular Sightstone. IMO, what could really help for supports and support tanks would be giving Ruby Sightstone some mana regeneration. +50% base mana regen would be a fairly decent amount.

Why mana regeneration? Because adding more health onto RSS would be abused by Lee Sin and Elise, who are typical jungle users of Sightstone. Elise would not benefit largely from mana regeneration because of her massive costs, while Lee Sin is an Energy user and thus would get no benefit at all from such a change.

What are your thoughts on this? Is there a reason Ruby Sightstone hasn't been looked at lately?
