Champion in game personality/back story

i watched the legends never die cinematic and liked it a lot. I liked how I got to see Garen's trials and the efforts he put into the becoming the Badass Demacian Fighter that he is now. It pumped me up to play some more of that silly spin to win square head and it was fun to play him again, but it didnt feel complete. I understood why I felt that way when i was playing ap rakan (rito plz dont nerf) with an afk xayah at fountain. Even though ive played a lot of rakan with a xayah the immersion of being a part of the hot duo was still there because of how they interact and how they always share some unique convo (which they have a lot of) and say things in battle to psych you up like qt saying "LETS GO CHAPANYA" when shiphtur creates some bard madness. Im not asking for a full vu update to every champ. No, just given them a lot more voice lines while walking, fighting, idle, or facing familiar foes. You know like garen with a brave heart speech when he's going in 1v5 in our ranked games lel.

Eh probably just a me thing since im into the role playing part of league a lot more. Well Have a nice day.

P.S. Rito plz comment
