Please give Rek'Sai a voice
Visually she looks pretty awesome and monstrous. Good work there.
On the audio side, I feel there is a missed opportunity with just giving her 7 minutes of growling with zero dialogue. Back at PAX East 2014 I was at the panel where Riot was discussing the reworking of Twitch. As the presentation explained, a champion needs to be fleshed out visually and with their audio. The presenters showed us how the same Twitch lines performed with a different tenor changed how the character came across in personality, behavior and motivation. It was a really nice panel.
Back to Rek'Sai. We don't have long bio's or champion judgements these days, so it's the ingame that gets across what makes a champion who they are. On top of that, she is the first female void creature in the game, and the first female 'monstrous' monster so leaving her speechless feels even worse. By having no dialogue we are left to wonder what is Rek'Sai aside from a seemingly unintelligent monster unlike the other established Void creatures. Is Rek'Sai hungry? Blood thirsty? Vengeful? Searching for something? Bored? What is does it mean to be Queen of the Xer'Sai? Is she protecting her "kingdom"?
Imagine new Sion with his old dialogue, Vel'Koz with only grunts and growls, Dunkmaster Darius with his base voices, Azir with just bird chirping. None of those would be nearly as great representations to those characters without their voice work and I hope you consider adding voice to Rek'Sai, even if it is post launch. A voice over along the 'feel' of the established growls could be amazing. A long, low guttural voice would sound great on her.
Thank you for reading.
