Sightstone rework idea

Let's be honest here is in need of a buff. and it feels horrendously DULL as an item. so i thought of a neat idea to rework the upgrade process. give different types of sightstones with different types of wards. plus it gives classes other than supports excuses to buy them as opposed to regular wards or trinket only. and encourages people to hunt down and blow up wards Ruby sightstone = builds the same as before. and now places up to 5 wards instead of 3. sapphire Sightstone = final cost = 1600 gold builds out of and holds 5 charges. consumes a charge to create a stealth ward that restores mana over time to allied champions inside the radius Emerald sightstone= final cost = 1600 builds out of and 2 holds 5 charges. consumes a charge places a stealth ward that provides a small amount of health regen amethyst sightstone final cost = 1600 builds out of and holds 4 charges. every 4th cast is now a pink ward
