Considering how odd and intimidating it was for me to start classes at 30 with all of the actions sitting there confusing me, the prospect of a full lev 60 and all of its abilities at once is kind of not good.
I am glad for palace of the dead because it allowed me to try the class with the abilities locked up at level 1 but I think it might cause some further degradation of the general level of job knowledge in the playerbase if we just have new players pop in to lev 60 jobs. Even setting aside learning curve for new jobs, the amount of burn out and running out of things to do would also go up fast.
Things like Wondrous tales, relic/anima, mentor system and hunt mobs can bring endgame players back to arr content and hw if Se really wanted us to legitimately spend some more time there so that new players were not alone. [SE can throw some glams/skirts/boots over there or a mount and I will definitely spend more time lol] I think its great how GC squadrons are making cities busy again that were not formerly busy all the time. Prior to this patch, Uldah was a ghost town pretty much but now people populate the area and intermingle with new players.
