This is less a suggestion, more a question. A lot of deities on our list suffer from either having one domain, or having domains that don't fit. I understand that we use what we have within NWN's and PotM's limits, but could some revisions be made?
A few specific examples I could think of while glossing over the various deities -
Callarduran Smoothhands [m] Earth N
Flandal Steelskin [m] Good NG
Hathor [f] Good NG
Hoar [m] Travel LN
This is just Forgotten Realms.
There are also deities that have inefficient domains that don't fully describe them, though this is an issue with D&D canon itself - I assume the point has been made before to change some of these and it was denied, but I will keep harping on the subject for the sake of my sanity.
Vecna - Evil, Magic, Knowledge... a God of necromancers and secrets, not having Death/Undeath or Trickery?
Bane - Destruction, Evil, Law... but no War or Strength, two of the pillars of his dogma?
You see my point by now. To clarify, again, this isn't a critique of the server, but rather D&D, and a question of whether or not we are willing to change this.
