I personally love the idea of Sightstone, and don't feel obligated to buy it. In fact, I feel like it serves a great purpose, and I WANT to buy it. It's cost effective, and gold is something that supports generally get less of. It also serves as a decent upgrade for the early gold income items. It helps to improve visibility without having to constantly buy additional wards. I personally would hate having to resort to purchasing consumable wards every time I go back. I love the idea of things that refresh when you go back to your base, whether it's sightstone, or potions. I really... really... dislike consumables. Except for those obtained from Klepto. But I prefer to sell those rather than consume them.
** They do mention this though: Support items will gain Sightstone’s active as their quest reward.
While this is a way to try and sneak it back in without making it feel like something you buy separate, I often get Sightstone long before the quest completes. Meaning, you have that much less vision for a longer period of time. If they change the quests to make them more easily obtainable around the same time people would generally have Sightstone, that would actually be a benefit
** And I just found out: Quest reward thresholds are reduced to 500 gold.
So, maybe there's still some hope... They're removing the item, but still keeping the concept. I guess we'll just have to see how it goes. It might actually be a good thing.
I originally read this post, wrote my comment, found the dev post, then edited my comments. If you actually read through it... it doesn't seem all that bad of a concept.
