Making "support" more "Fun"
You guys have tried several times to get more people to want to play support. By "play support" I assume you mean "Not go top laner in bot lane / minimage in bot lane" etc.
How about making sightstone like the Jungle item?
Suggestions :
Make sightstone a basic (not combined) item. Lower the cost, eliminate the health.
Mid tier upgrades : Ruby (adds health, combines with ruby crystal) Sapphire, (adds mana, combines with sapphire crystal) and Regen (health and mana regen, combine with faerie charm and rejuvenation bead) These can be combined with gold items to make the three Eye items (for Equinox, Watchers, and Oasis, respectively)
Full Upgrade sightstones : Healing (combines with Forbidden idol, 10% cdr and an increase to healing bonuses) Damage (combines with Caulfield's Warhammer, 10% cdr and a bonus % to bonus AD) Magic (combines with Fiendish Codex, 10% cdr, bonus % of AP) Protection (combines with Glacial Shroud , 10% cdr and a bonus % to Armor) Magic Resist (combines with Kindle Gem, 10% cdr and a bonus % to MR)
You might place a cap on any of the bonuses to make them less useful to carries, while still allowing gold-starved supports to do some kind of damage

:That sound nice
