I don’t really have an issue with 100% rep guilds, but I’ve noticed that a lot of the previous 100% rep WvW guilds have stopped enforcing it (because the guilds are fine with their members repping other WvW guilds on their non-raid nights or when their raids are cancelled).
There are benefits to 100% rep – such as always knowing what’s up in your guild, being aware of changes that happen on the fly, last minute cancellations, and never missing out on guild events. If you’re in a friendly guild, then you’re also bound to make new friends and always have a wonderful place to ask questions. (But if you’re in a guild where people don’t participate in events or do things together, then this wouldn’t be a primary concern of yours.)
I feel less connected to the other members in non-100% rep guilds because I don’t talk to them or see them as much, and I definitely feel the 100% rep guilds have a tighter community (in my experience). There are, of course, those really awful guilds that are going to be terrible no matter what.
As others have mentioned, if you really feel offended by such a simple thing then maybe this guild isn’t meant for you.
That sword looks like it might need to be in my wardrobe.
