I dunno but in d1 I was a big prison of elders, Siva and Fallen fan in general. Variks voice lines were my favorite so when I heard Variks speak in the trailer I noticed he learned some grammer. I thought it was a nice character development, but still gonna miss that special grammer. or atleast way to speak

I don't think he used special grammer. It was probably kinetic, or heavy grammer.
