Placing a ward should give you gold
- Increase income of supports (especially those with no ADC to get assist gold from).
- Encourage teammates, the ones too unintelligent to understand the power of vision, to ward.
If you're a support, you should always rush a sightstone, as they pay for themselves after 11 wards placed.

Oh really? Then you buy a sightstone and spam wards in the spawn zone. Now Lee Sin will win every game. (Unless there's two Lee Sins)
To all the feedback from people bitching: have you every heard of "cannot occur more than ' ' number of times in ' ' amount of time" or charges, personally I think it's a great idea to get more people to ward and completely controllable. Some people are just irrational lol
