This is wrong.
The role type questlines are the retelling of the WoD and not the job quests.
The Job Qest will be condensed into a single quest at level 80 instead of spreading the story over multiple quests at different levels.
Also wrong.
The DoH/Dol system is a kind of costum deliveries and has nothing to do with the job/class quests.
Because most role actions were niche for specific situations ore just plain stupid, so they reduced them to the "needed" amount.
(Tanks: 7; Healers: 6; Meele: 6; physical Ranged: 6; magical Ranged: 4)
Skills that were so situational and mostly unused and avoided.
So yes, in the one or the other way this things were requested.
1)+2) Not directly requested but: Less divided story of job quests with aditional content for the lore and background with the side effect of potential additional leveling content is always a good change.
3) It was often requested to rework the role actions so "usless" or "extremly situational" skills would get purged or reworked.
4) It was more a silent request by neglecting the enmity skills and avoiding tank stances as much as possible and so they just followed the current highlevel gameplay and made the tank role more aproachable.
