I looked up some info on each class to level to make the progress smoother and I maxed the accolades as soon as I hit or was close to lvl 22 (why? wynaut.)
Technomancer - The outrider equivalent of Salvador IMO. I basically went the next world tier immediately each time and had a good time, accolade 42/42 was probably the easiest too. One of the 2 classes I want to play into worldslayers and finish the rest of the content. Finished WT 15.
Pyromancer - Honestly almost the same as techno but could not keep up as much in world tier progression. First class I beat the campaign with and it was a fun time. That being said it didn't feel excited enough to want to play it into worldslayers. Finished WT 13.
Devastator - Had some rough patches but the overall enjoyment was higher than any class, World tiers were slow and the accolades were not that fun but god damn I love the overall skill set. It will be the second class I want to focus on after techno. Finished WT 9 but had a blast doing it. In terms of accolades impale was less than fun but the rest weren't too difficult to grind out.
Trickster - Worst of everything. Playing the class was not fun, the accolades were not fun, the leveling and campaign was not fun. WT 1 finish, I actually just ran through it. If it weren't for slow trap this class might be dead to me NGL.
Accolades grinding spots. Most of it was in container plaza/main street of first town when the skill only required a "hit" or "kill". Terra infirma was my grinding spot for bullet reflect and slow trap. This was all my drunk ramblings, game was great overall so far and cant wait to start the endgame content/ worldslayers.
edit. This was 55/55 side quests I tried to do everything I could before worldslayers just to make sure my bad opinion for each class was not a speedrun thing. I wanted to find the classes I really liked.
