I know a big point to guild wars is being in a large guild, but not all players (and I know im not alone in saying this) want to being in a big guild. I am currently in a guild of 7 with about 5 actives and there are people with even smaller guilds, I feel is is discriminatory to only have guild missions that are achievable by 10+ guilds. My suggestion to Arena Net is that they implement smaller guild missions, little objectives achievable by 2-3 people but make then take much longer to earn merits, possibly add an extra guild currency that you earn from the little ones that you can trade sat 10 or 15 in for a guild merit and maybe something similar for the individual tokens. This would still encourage people to be in larger guilds due to how long it would take to gain merits but would allow smaller guilds like mine to gain access to guild content.
