Right, because new players can't enjoy or be helpful at towers?
The "noob recruiting" thing is popular, and always will be popular, because staff refuse to make it illegal in any way. You act like it's entirely a bad thing, when I'm sure there are many new players who actually appreciate the opportunity to tower with a guild.
I've already suggested 100 times in the past that staff add the requirement of only allowing someone who has had a tag for 24 hours to enter a tower, but it's not happening. We deal with it and adjust accordingly.
Not to mention, you shouldn't view this as something negative. I'd have been using it in my tower guilds to remove the guild chat permission from everyone who isn't a leader or a temporary leader, because I personally feel like it'd allow my guild to function better. Then, sometimes, I'd love to guild spar with people but not constantly deal with their spam in guild chat. If it's my guild, shouldn't I be able to control that?
