Unpopular Opinion: Future Market is a drug
Ever since it was released, I think I had it used on 95% on my games throughout all roles, mostly as secondary runes. The gold debt allows myself to be ahead of the corresponding enemy by an assist to a kill which gives tremendous advantage during laning phase. With it, a lot of times where I was short gold to complete the item, it let me complete it and other times, those 3 red potions gave me the ability to out-sustain my opponent. Without a doubt if Future Market were to be removed next season, my chances of winning a role will severely plummet. It isn't the rune anyone cares about, but the rune everyone needs.
