I wouldn't call it defending since if you've played since Alpha it's ok to admit the game actually improved since then and especially since release, it just hasn't gotten any content. The current content isn't enough to satisfy everyone as guildleves were described to be the content for people who have a little time to play...however the game released with only said content so it's easy to understand what some people could mean by "the game has lots of content" because by definition, guidleves, sidequests and the main story arc is content, but it's subjective, because people only deem "dungeons" and raids as content.
I know it doesn't take me 20 minutes to clear my inventory like it did at beta and release and I know the game actually registers my actions unlike it did at release..so the game is improving, but I don't think anyone is defending by saying it's getting better because it is for all intents in purposes.
