I get why it annoys some people but once a new expansion comes out people will forget their optimal rotation on lower levels. Stat weights will change, hotbar setups that were optimized for lower level play will change to work in new skills, and abilities that used to be a necessity will be removed. The majority of guides for content will come out while said content is still current and recommend things like scholar having stoneskin crossclassed or "You need x amount of accuracy to be able to hit x". The game is going to keep changing and adding brand new challenges to make up for older things becoming easier.
