I'm can say with confidence that at least 90% of the people who see Lucio-Ohs cereal for the first time reads it as Luci-Ohs. 

That's because Luci-Ohs sounds a lot more fluid and rolls off the tongue much better than the cumbersome sounding Lucio-Ohs. This fact alone has changed people's opinions on this spray from amazing pun to an amazing oversight.

Make Overwatch a better game. Change the Lucio-Ohs spray to Luci-Ohs. The game is literally unplayable in its current state.
