Honestly? This is one of the worst states the clan world has been in and I have little faith in the clan world being able to bounce back due to lack of care from both Jagex towards clans/clan communities, or even with us as the current gamers in the clan world. I have been around since 06, watching, observing up until 08, and right now, the type of community we have built for others to even consider joining: is disgusting. Some of us are good people, able to help others integrate into communities, adapt to the F2P (or P2P) way of life, but for the majority of others; we have created this community where egotistic, borderline obsessive egos, have taken hindsight and thus the negativity some have caused have turned many others, and I mean a lot of players, away from the potential possibility in joining a clan. To be even more critical, I think at this point those not involved in our type of competitive community would prefer joining a PvM and Social clan, rather than a PvP/competitive one.
My view might be harsh and some might take it whatever way they want, but it's the truth. Some of us as a collective unit have turned what was potentially a nostalgic opportunity in regards to the clanning community, into a place where there will be nothing of nostalgia or a clanning community in the coming years. To steer away from the harshness of the truth, we as players can only do so much to make better of what is left. Can we broaden people's perspectives and try to get people to give clanning a shot - simply, yes. But the question is whether or not we care enough, or have the actual ability to do so. Most of us are older, with responsibilities, or simply do not care enough anymore. Personally, I have moved onto other games, but I feel like if we all had or have the time to put a better outlook on our clan world, we would be able to develop an influx of people. If we were to have more support from Jagex, let's say, other than the [overdue] Jagex Cup and had some spotlight on the competitiveness whether P2P or F2P, people would have a better view and be instantly attracted. If we as players were to better support what we play, in terms of the egos, negativity, whatever, then maybe others wouldn't be so cautious in joining our community.
Tl;dr - a community is what it is made of. From administration to the people within.
