Can Riot maybe buff the support role income? or make sightstone more useful late game?

I understand the basic idea of support "you are suppose to help your team to victory", but i honestly do not understand the reasoning behind making a role that is expected to run on greatly reduced income. This becomes even more of an issue when you consider that most supports are having to drop 1200-2000 gold (sightstone and boots) before they can start building their core offensive/defensive items. Add to this the fact that as a support you are usually running a couple thousand gold behind your allies. Even with the support items (they help but i think they could do more), you are often at least 1 item behind you allies. Would it be possible to put a mastery deep in the utility tree, something that gives like 25-50% to a character if an ally kills a minion near you? I just would really love something that made it easier to be on par with my allies item wise.

Could we also talk about Sightstone in general as an item. Personally i think it's a real pain to deal with. You have to pick it up early to maximize it's vision potential, so that off sets your ability to buy other items that you might need for your core build. In the late game it's almost painful to have it in your inventory, since 150 health is really not worth an item slot... However you can't really give up the vision it provides around the map. The charges only restock when you visit the shop so you are basically forced to port back to base every 2-3 minutes if you want to keep vision up in multiple spots. So you can't really siege an area (tower, baron, dragon, etc..) without risking running out of wards and being blind to your enemies movements. Would it be possible to maybe have the item regenerate wards at something like a rate of 1 per 90 seconds? Keep players from having infinite wards, but also keep people from having to return to base over and over again just to recharge an item.

currently has the issue of being the only item that has to be constantly recharged to be useful. I am aware of flask existing but you rarely ever see a player rocking out with a flask in the mid to late game. Sightstone is such a core item for a team that you will always have at least one player holding one as soon as it can be picked up.

TL/DR:
It sucks always being a core item behind as a support.

Sightstone makes you delay your core items early game, and the stats and usufulness are subpar to horrible late game BUT you still can't get rid of it.
