If NA and Korea dont want the new ranked system, still give it to EUW?

Like, I really wants the new system to work and I'm ready to give it some time. The issues seems different then dynamic que and easier to fix. Still a lot of ppl that tried it seems to not like it, but could be that's because most ppl that like it don't say it. But at least let us EUW players try it before that pls. I was really excited to be able to play different roles in ranked and not just the usual top lane and I hope not the backlash will stop us from getting it.

EDIT: I'm not saying NA or other regions should keep the new system if they don't want to, but that EUW could keep it if they wants to even if the other regions go back to the old system. Pls read the post before you downvote.
