Problem:
Damage Casters are not on Par with the melee damage classes in a raid setting.
When an Air geared Cleric meleeing with Panther outdamages an Air geared Magician, you know there's a big problem.
Suggestion:
Tweak casting times and spell damage to fit into the current damage order.
Example:
Newly 70: 1600 DPS
SSRA Gear: 1850 DPS
ToV: 2250 DPS
Sleeper: 2700 DPS
Fire: 3300 DPS
Air: 4900 DPS
Fear: 6000 DPS
This would have to be tweaked depending on player feedback, but its really what is necessary to bring casters in line. Also, the main nukes for the casters need better negative resist mods, nothing is more frustrating then casting 5 or 6 nukes for 0 damage.
Problem:
Due to the raid mechanic of rampage on the server, pets are mostly a 1 hit wonder on serious raid targets. Pet classes are designed with their pets as a large portion of their characters abilities. Making the caster take time out of their DPS casting to heal their pet further pushes the disparity between caster and melee DPS.
Suggestion:
Make pets IMMUNE to Rampage. Give each class a AE spell ward buff for their pet that lasts 4 or 5 times per cast. So the pet caster still has to keep some kind of an eye on their pet if the encounter has AoE spells, but at least it can contribute to the fight.
