>>717428517 (OP)
DPS role not having as much depth and interaction with their party compared to tanking and healing, or responsibility (no one cares if a DPS dies, but a dead tank or healer is wipe).
Tanks and healers also DPS and can swap to DPS role, not so much for most DPS.
Most DPS never played, and will never play other roles.
Ratio of roles needed in a party/raid and actual role distribution among player characters leading to an unbalanced state of DPSs being expandable while tanks and healers are held on a pedestal because too few play those roles. This leads to an unhealthy pressure and extreme feeling of competition amongst DPS that no other role has to deal with.
DPSs only having to do damage and know what to do during a fight and nothing else, while tanks have to coordinate with their other tank in raids and lead the party/raid, manage healers big cooldowns, call out mechanics over voice chat because DPSs are drooling retards anyway, call out who to combat rez, call out what to do, where to move, what to attack...
>How to fix this?
Give more tank specs to DPS classes.
Give DPSs more interaction with their party beyond threat redirection and tanking/healing abilities from hybrid classes.
Reward mechanic execution and player survivability over pure damage output by making said mechanics more punishing.
Make usage of DPSs cooldown (mitigation, healing and DPS) matter as much as tanks spreading their mitigation tools and healers their healing cooldowns.
Introduce more fights with bosses/adds that can't be taunted, have random aggro/fixate to enforce proper cooldown usage from everyone to control, mitigate, survive and defeat an encounter without relying on the tank mass aggroing everything and absolving other roles from ever using their full kit.
