Is that assassin with domination running ravenous hunter or ultimate hunter? Is that adc with precision running presence of mind or coup de grace? Is that 'squishy' support running bone plating or overgrowth? Sure, you can often figure it out just by paying attention but it feels like when you,realise, it's too late. That feeling when you lose a duel you thought you could win with a sliver of health and you go "Oh, he had ravenous hunter" or when you think you can burst someone and go "Oh, he had bone plating". This sometimes valuable information should be on the scoreboard or even in the loading screen. It's too impactful to just be hidden.
