For example nerf the damage output of the
Dr/wl & s/w with 40%-50%
All other good dps classes with 25%-35%
The remaining mages with 10%-15%
You know that mages are still top dps? Oo ever played with a good mage in the group? Only think where mages are not top is 2-3 second burst single target as in your example.
If you want nerf damage output, take a look on support classes, bcs most of raid damage coming from them.
For example (after the nice healer changes! Ty for it!)
WL/m is mainly a support. You can let 6% buff scale with wisdom or heal bonus like surge of awarenes could scale with wisdom or heal bonus for example. Some support skills of the class scale with heal bonus
Warrior/priest: let the HP/crit buff and the buff from berserk scale with strength. Warrior/priest is still a dps and can do damage.
Champ/druid: let knowledge of destruction and the patk/matk buff scale with stamina (for Tank/shield form) and/or strength. This class is a good dps!
Scout/priest: let raid dmg buff and attackspeed buff scale with dex/str or dex only. This class is still a good dps!
Mage/warlock: no change needed. Forgotten black Magic was changed in the past, that it scales with matk. 👍 For it
These are just a few thoughts. The supporter classes should be more integrated. I often see classes like ch/d, w/p and s/p played in cloth gear doing nothing else but using 2 skills every few minutes 🙈
