>>4112358I mean, it isn't the author being a meanie towards Rin or anything, she probably likes her given her previous works like this one, it's just she gives every character something, even the irrelevant characters. Later on, there are even chapters with no Shirou.
So yes, it should be given a low priority on your list.
>>4112766>Anime or manga?I'd say manga, but still you can't go wrong with the anime and Rin's voice.
However, even if you went with the anime you will still have to check the manga from the first chapter if you decided to continue since the anime adapts different chapters. There is also padding so some details will be different.
