I see no reason why we still only have one flavor of Sightstone

And it's RUBY

Health is cool and all, and it's not unlike its a stat what can't be used on most supports anyway, but really your poke and utility supports don't make as much out of it as tank supports do Since we have had a more diverse work go into selective items into sub roles items, such as the entire jungle item list, can we please see some kind of extra diversity injected into the support role too?

Supports do already have one item dedicated to sub support roles, the gold generation items are a good thing, but you have to remember that every support has to dedicate 2 item slots to 2 core support items every game, so give us the freedom to let the sightstone portion work optimally for all supports and not just tank supports.

Tanky supports already take up 90% of the support picks anyway and are far far more favored in the meta then utility/poke supports, so why not give them both a different sightstone to help them see more play, one centered around giving mana regen and mana, and the other giving AP

Disclaimer This isn't a buff to sightstone, think more of a sidegrade, the idea is to still keep the different sightstones money to stat ratio not worth it so that other roles cannot abuse the items, all while giving supports who see little play such as Sona and Soraka (examples of 2 champions who can utilize the AP or Mana stone much more then the current HP stone) so they get as much benefit from buying into a sightstone as support champions do who scale really well with HP like Leona and Thresh, 2 champions who have been very popular for OVER 2 YEARS.

Rename Sightstone into Garnet Sightstone (Another red gem) and change the icon into a more faded red then Ruby Sightstone

Lapis Sightstone - Builds out of + and provides 50% increased mana regen and 150 mana Sapphire Sightstone - Builds out of Lapis Sightstone + and provides 100% increased mana regen and 400 mana

Opal Sightstone - Builds out of and provides 30 AP Amethyst Sightstone - Builds out of Opal Sightstone + and provides 70 AP

Perhaps even make these sightstones only buildable if you have and their upgrades, this would fix non supports being able to abuse them

I am no geologist so I probably messed up with the gems, but I hope you get the idea, both these mana and AP focused ward spitting items would help the utility and ap supports out there who see next to no play, instead of painfully buying into damn health when they just don't really need it.
