No it doesn't exist anymore sadly, here's to say in the future they won't start it again though.
Here's what Cipsoft thinks of Focus Groups currently:
Why didn't you make a focus group?
While focus groups can give valuable insight, they only constitute a part of the player base. Participants have their own ideas which are at times hard to reconcile with everyone's opinion. Moreover, some players who could provide great feedback might for whatever reason be unwilling or unable to take part in the discussions while still being affected by the changes.

What can we do to share our opinions if there's no Tibia Council now?
Also, a Tibia Council group will last for a certain time only, and it will focus on specific topics instead of broad areas of interest.
However, we would like to run this as a pilot project first so we will start with just one Tibia Council group. This group will focus on hunting grounds in Tibia.
