...i would say it's probably ACTIVITY, closely followed by KNOWLEDGE ACTIVITY - be available online for Raids, Nightfalls, Crucible, etc. if you're not there to play it makes no sense to be in a Clan KNOWLEDGE - not only knowing different strategies for both Raids, but also general knowledge about the game, being able to help your teammates choosing the right weapons, knowing the perks, help them improve their game, etc. (there's loads to be mentioned here, you can send me a PM and we can discuss in more details) ...but most of all, be friendly and helpful, people will appreciate that ;) of course we all have bad days, i myself have learned not to play when im not in a good mood
