A.) Herald is the hardest cabal to get into because... well its dead and has been for a few years (rarely see a leader, not much in the way of consistant inn sitters anymore, etc)
B.) The RP standards of herald tend to be beyond what at least I would describe as a true newbie (even if they are all lesbian felars who use the hug social way too often)
C.) Heralds don't have powers that help them outside the inn.
D.) While I always assumed heralds were supposed to be more go out into the world oriented they are really just sit at the inn because they don't participate in cabal wars in any way. This kind of limits them to explore trips and sitting around. Explore trips happen less often and for the most part if players are just going to be sitting around for extended periods of time they log off these days.
