As a Bard and Machinist main, I can finally spam my aoe's without worrying about TP anymore. I for one welcome the removal of TP and do not miss it!
Running old content is boring and limiting as it is with your 5 skills. I do not see a problem being able to finish old content faster. I dont understand what your problem is, but if you got an issue with clearing dungeons faster or feel pressured to speed run, then play a tank and decide the pace by yourself.
