If it becomes anything like the "active support" involved with the A-League then it would definitely have a negative impact of the fan experience (for the rest of us), in my opinion.
The last thing we need is a group of supporters that think they're somehow better than the other supporters who actually prefer to watch the game and cheer when relevant, rather than dance around, chant/sing non-stop, bang drums/wave pom poms/throw flares, break seats, copy overseas trends, get into fights with "active supporters" from other clubs, and cost the Eels and arm and a leg in extra game day security and poor publicity! ;-)
Our membership looks to be going fine (over 20K), and when our team is playing competitive footy our home crowds (at our real home - Parra Stadium) are close to capacity with great atmosphere. Keep the existing Swarm bay/s, and no need to change anything until we are hanging the Sold Out sign in front of the stadium three or more times a season, and ticketed membership is the hottest ticket in town (with waiting lists to join).
