Improvements are a matter of opinion. Having quests reset when you change jobs is not an improvement in my mind. It is the thing I detest most in other MMOs because I am forced to roll alts to try other classes and have to run the same quests. I hate it with a passion. You may not like the options but they have given you many many options to level. Quests, Dungeons, Leves, Guildhest, Hunting Log, Grand Company Hunting log, flat out grind and get mats for crafting in the process and of course FATES. You complain about the grind but sorry doing the same quests over is just as much a grind just under a different veil
