There was rumour (and it should have been truth) before PoP came out that people would be allowed a one-time chance to alter their deity.
I created my wizard back before there was a single deity-specific item. Luckily I was semi-RPish and chose a god, but I know a LOT of people that are agnostic and complain about it thoroughly. Especially with the advent of PoK, and so many other towns where people are universally accepted regardless of race or deity (read: race/class/deity is all but useless these days in any modicum of an attempt to be roleplayish)
I miss the old days where people had respect for people who played Dark Elves or Iksar because they were so hated everywhere, and had a hard time getting around.
