I like your point on speed and i think steps should be taken to allow speed to be built on more jobs. The main way i see this happening without very broad reworks is allowing jobs with combo dots (mnk, drg, pld) to extend their dot like reapers deaths design. This makes is so if you build full speed and arrive at your dot refresh early, its not the end of the world, and after enough sustained uptime you skip an application. This doesnt account for the other kinks of speed stacking like missing the very important 2 min line up (another reason the shift to 2 mins is harmful to the game design) but baby steps.
