its also impossible to have a hub for every alignment or persuasion, i think having just a netural, good and evil hub aka, Cordor , kohilgen & Tarkuul is a big enough ask when these days we dont max out the server slots on both servers like we used to. If anything these citys should be "molded" by dm to make them more agreeable to the multitude of various within the good, the evil and neutral so that there is a place of rp for all in these sites. Like having more than just a select few faiths and organizations.
In forgotten realms there are citys that house directly opposing churches, and that my friend inspires a lot of interesting RP why not go build a church to whatever demon god you want in tarkuul, request it or something, and same goose for anyone else then you and all your chaotic demon worshipers have a place to hang were they will get both negative and positive interactions
all works in theory hey, but without this direction being guided by the staff it will always end in fisty cuffs and dead body's. Although Tarkuul has its laws, and technically so long as you abide by them there is nothing stopping you taking up residence there or requesting all manner of additions such as temples or "faction" houses i suppose. Same goes for the Cordor and Kohilgen, with the right "twist".
Well that's my 2 cents, perhaps a little off topic, but i figured i should just say it how is ee it >.< no point making RP areas based, there are to many dam areas.
