You guys can have your male channelers and all that. I just want a wolfkin. I also loved the World of Dreams and the possibilities in it.
Remembering all the different magical things people could do kept me from pursuing an Aes Sedai on Cuendillar. Going away from that with another type of character was easier for me to get into. Plus, many of them will need Warders as well.
But, I think there does need to be a quota cap on how many PCs there can be of a certain type. Maybe a soft quota, one staff has to monitor early on to see if they think there are too many people trying to play this or that so things can be more balanced, but if you have a world full of male channelers running around, I think it starts to lose its uniqueness.
Maybe what we're looking at seeing in-game is the main focal point of things, with the commoners left as NPCs or in the background in general, but having no limits runs the risk of diluting the pool and making the abnormal normal instead.
I definitely agree on limiting Darkfriends/Black Ajah, and any that exist should probably be in contact with staff fairly frequently in order to help keep them coordinated. It did get a bit out of control on Cuendillar.
