i think spike does it right because they(Soniqs) aren't on it yet untill they play more matches probaly. Im not saying spikes rating is better it is actually really bad with how long it takes to update.
NGL these Soniqs guys are pretty bad lol. Like I know NA is the strongest region in valorant and all games for that matter, But was all the hype really needed. They obviously just under performing because the NA giga chads are so much better then the AU bater males.
From the closeness of the match against RNG is looks like they are in the correct position between approx. 8-16 where everyone is close together. If they continue loosing more matches against opponents of that rank they will go further down. But that match against RNG could have gone either way.
