Going OOM with a Muramana is what you WANT to happen, that is what it's for. You burn through your mana to amp your DPS, if you don't burn through your mana then you don't get that DPS.

If a marksman has 2000 manapool with a Muramana, then Muramana will give them 3200 damage (80% of 2000 is 1600. Double that for 3200). A KogMaw who attacks 4-5 times per second will probably get that damage number in under 5 seconds, whereas someone who attacks much slower like Caitlyn will need 10 seconds to drain her pool. Thus Kog builds Muramana and Caitlyn does not.

In order to make use of Muramana you need to ether attack ultra quickly, or have spammable single-target abilities to weave in between your auto attacks, you want that damage to come out quicker not slower.

There is one final use for Muramana and that is on an AD who doesn't actually benefit from the damage at all and simply uses the item to boost his manapool. Varus is the only one who does this.

Jhin doesn't fall under ether of these situations, he attacks slowly so doesn't get much damage from it, and doesn't go OOM so doesn't need the mana.
