Why are Melee and ranged DPS roles mostly support and not focused on damage?

[Deceptus]

Why does it seem like melee and ranged magic DPS roles are lacking?

Tank role abilities decrease damage, increase healing, manage aggro etc.

Heal role abilities increase healing, allow for swift cast, sure they have some terrible abilities in Break and Cleric Stance only being 5%.

Bards and Machinist roles make sense. They've always been support and the roles reflect that accordingly.

However Ranged Magic has absolutely nothing that increases their damage, and neither do melee dps. These "Role Abilities" don't fit their role at all.

Crutch and Arms length are probably barely ever used. Feint's CD is way too much for a 10s ability.

Break is useless for ranged, as is Drain (it doesn't heal enough). Erase doesn't work on enfeebles, just dots. Addle is as bad as Feint for the same reasons. Apocatastasis is tough to time, because you never really know what attacks are physical or magic even if something looks like and appears to be magic.

A basic aoe move would help for melee dps when you're synced down and don't have any aoe at all (DRG don't get their spammable until level 40 and ninja don't until 42)
