Riven and Yasuo skin Name Rant

So yes new yasuo and riven skin woop woop, i myself love playing both champions despite being b5 trash, i like the skins but i have simply two problems. 1 dawnbringer and nightbringer, cool naming at all but looking at the skins its not the theme i can see, i see riven as a bit angelic and yasuo as demonic so im seeing more of a Light Guard and Shadow stalker kinda feel to it, and second yasuos ult just feels unsatisfying to watch being so slow as yasuo is typically a faster champion. and thats my rant. im outta here
