Relic shield needs a rework?

I saw from phylol's video and I thought that relic shield needs a rework. https://www.youtube.com/watch?v=vPPhh5Oh_Po I've realized that tanky supports need a better method to generate gold than just executing creeps. As of now spelltheif and gold coin are far more reliable at generating gold because with shield it depends on what minion is executed. Having the Marksman use Relic shield gives health, health regen and once the quest is completed a shield. It also gives support more gold income helping them to build better items. I would like to hear some ideas about how would the community's ideas on a fix.
