Liquid plays in NA. They do visit EU though and play because the org is based in the Netherlands, yes.
But, they are not permanently a EU team. They go back to NA for qualifiers and more, something JKS doesnt want to do.
JKS is not joining a NA team. Really simple to understand yet i see hundreds of people spamming "JkS LiQuiD".
JKS and Jason Lake have both said he wants a EU team, not a NA team, not an Asian team, not an Oceanian team. EU TEAM.
JKS is most likely joining OG really soon.
