I'm not of the same opinion, I've been alche/herb in vanilla's days and on Darrowshire the herb system is broken in some point: there are too few spown points or the respown time is too long.
I played in a server with always the queue, and at that time the server cap was 3k if I'm not wrong, but I'm sure that the dreamfoil weren't so few, the Icecap were a bit problematic with the mountain silversage too, but in this server the soil is too barren for some herbs, dreamfoil at the top of the list!
I'm 60 from 3 mounth at last, and I've tryed Silithus, Burning Stepps, Azshara, Winterspring, EPL and so, but the dreamfoil are too rare for a blizzlike, it's broken, there's no doubt. Futhermore I remember to had the same feeling for some other herbs diring the livelling, but in a minor way.
