I Don't See the Point of Omnistone

As the title says, I don't see why Omnistone exists. They didn't like that very few champions were taking Kleptomancy, so instead they made a rune that literally guarantees 100% of the time that there would ALWAYS be a better option for every champion in the game than the rune that they created.

Sure, the idea of Omnistone is fun. Your runes cycle around between different ones that you could feasibly proc, and that produces a good environment in the name of fun.

But you also have to concede that it is solely for fun due to the random aspect of it. Because it's random which rune you get, and because you have no way of knowing which rune you'll get next, you have to play around it with that in mind. It's unique and fun, but it totally and completely removes any chances of it being competitively viable on any champion. Why would I take this rune, which randomly shifts me around between different runes (some of which are always suboptimal to not have as your primary rune - I'm looking at you, Dark Harvest, being almost completely useless if it's randomly rolled from this - and all of which are better for certain champions than for others), when I can take a rune that is always optimal for my champion?

To replace a niche rune that a few champions used, they created a useless rune that no competitive player will ever use for any reason, because there is no reason to use it.

So how do you fix it? Do you buff up the runes that it gives you? Obviously not because then it becomes overpowered. If the runes that it gives you are stronger than their base forms, it almost always becomes better to take it than to take a different rune.

How I would have fixed the issue that they had with Kleptomancy was by doing something similar to what they did with the passive portion of Zoe's W: Spell Thief. This item randomly marks minions with balloons to drop Summoner Spells and Item Actives that Zoe can then pick up to use with her W. So, do the same thing with Kleptomancy. Say, every 4th minion kill that you get, you will receive an extra 5 gold for. Occasionally, some minions will be marked, very visibly, to let other players know that, if the person with Kleptomancy kills that minion, they will get randomly rolled consumables from what Kleptomancy could drop.

This way, it benefits the late game scaling champions even more by giving them access to extra gold from farming while also giving the opponent opportunities to combat against their opponent getting the randomly dropped consumables.
