Hi @Sai Edge.9306, your post threw me a little, as I never quite expected to see the two extremes of "friendly place to meet players" and "cult" in the same sentence, but I will try to answer the core line of your message.
As said in our how-to-join/rules "This is a community centred round an online multiplayer game; therefore, player engagement is important". The WAHA guild was built for its community, and it is only through the players actively interacting with it that it works.
In terms of activity, what we ask is that new potential guild members aim to join for at least 1 event per week (more if possible). If they seriously want to join a guild, then interacting with the guild by playing with its members simply makes sense. But also, that is an aim. Life can get in the way and interest in a game can wane. All of these things are totally understandable, as long as when the player is actively playing GW2 they want to actually play with the guild they are part of. Otherwise, why join a guild in the first place.
In terms of representation, it follows the same above reasoning. We want our members to understand that they are part of a community. By setting your representation to the guild whilst online, you give the message to others in the guild that you are playing alongside them for community, that you might actively engage in the in-game guild chat, and that you want to be part of the guild. Conversely, guild members seeing others in the guild online but not representing can give the message that they want to play the game, but not with them. For a guild built specifically for content types (raids, CM fractals, etc.) this might be okay, but this is not conducive for a guild based on community.
If the above is incompatible with the type experience you expect from being in a guild, that's okay too as no one is forced to join us, so I wish you the best of luck.
