Stop Throwing Random Clan Invites!
What bothers me more than Blitzers that never miss and Hellbug Archers that pop up by the dozens are the random clan invites that fly at you when you finish a quest, an Arkfall, or walk into an outpost and you get hit with like 10 of them. I'm not in a clan cause I want to meet some people, play with them a bit to see if I like them, and then join their clan maybe. Throwing out random invites is really annoying and unprofessional if you're trying to build a clan.
I'm older than most people playing this game and want to make sure I'm playing with like minded people. I've been in too many clans in other games that turned into pissing contests among the young immature players (and some older immature players) internally, or with other clans and gamers in general giving my clan a bad image. I damn sure don't feel like dealing with that crap in this game.
Try grouping up with someone, playing with them for a couple of hours, and then asking them if they want an invite before just spamming them with random ones.
