This Equipment Preview feature has been requested a lot on the beta forums and on reddit, so it's nice to see it in the next beta and ready for launch. Just another case where one can say "ArenaNet really does listen to their playerbase", by adding all these quality of life features to the game. Though don't go yelling on the forums for "Raids" & "Open World PvP" and expecting those to be added in.
