How about making sightstone upgrade in some way after generating X gold with support items?

My idea is that Sightstone/ Ruby Sightstone gets a little powerup that gives you something when you generate let's say 500 gold from your Gold Income (support) item.

This guarantees that junglers aren't getting this benefit and gives supports another reason to actually try to use the passives.

Here are some suggestions (though kinda random and probably not interesting) just to give an example.

Talisman of Ascension

Upon generating 500 gold with the Favor passive, your Sightstone/Ruby sightstone gives you 25 out of combat movespeed for 2 seconds.

Frost Queen's Claim

Upon generating 500 gold with the Tribute passive, your Sightstone/Ruby Sightstone wards that expire grant you 0.5 ability power.

Face of the Mountain

Upon generating 500 gold with the Spoils of War passive, your Sightstone/Ruby Sightstone wards that expire grant you 0.5 Armor or Magic Resist (whichever is lower)

What I had in mind was the types of supports that tend to buy these.

• Talisman is bought by ranged utility supports that mostly rely on using their spells to help their carry so I don't think they need any combat stats.

• Frost Queen's is bought mostly by pokey supports that wouldn't mind doing a little bit more damage.

• Face is bought by tanky supports so they need tank stats I guess.

Sooo yeah, these could be extremely useless, overpowered, random or just plain boring but this is my idea. So what do you guys think?
