Use the same mechanic Knights Vow has to improve Gold Items for Support!
RIOT is wondering how to buff supports gold gain without making it abuseable for solo laners, and honestly, the answer is easy: Make it work like Knights Vow or Zeke's Harbinger.
The first two support items get an active that chooses a champion ( The ADC) as a partner, and then the gold gain effect (or maybe even some of the stats) only kicks in when you are close to your partner. Limitation is removed when your partner is dead and for maybe 30 seconds after he respawns, so the support doesnt suffer when the ADC dies in a gank.
Bam, you can now buff Support Items without a risk of having them abused by solo laners or junglers.
You are welcome!
at the bare minimum (and only if you go for one of these
) otherwise that's a third must buy item. So now you want us to have a 4th must buy item? screw that!
, not creating new items
already give actives and the eye items are not going to get those type of actives without increasing the price of them by a good margin defeating the purpose of the eye items (it would also make no sense to lose that extra gold generation when going to the main items). Also this would make those 3 items have an increase in price or rebalanced around having the dumb active that they don't even need. You already get more than good enough gold from those items to begin with. Once again, NO!
