I think it would great to implement a new addition to the daily Duty Roulette list,
Duty Roulette: Raids.

It could pull from the player's currently unlocked raids list and, we could have both a 50 and 60 version.

Level 50 version: Duty Roulette: ARR Raids

Labyrinth of the Ancients
Syrcus Tower
The World of Darkness
Binding Coil/ T1 - T5
Second Coil/ T6 - T9
Final Coil/ T10 - T13

Rewards: Exp. for players over level 50, Allagan Tomestones respective to the players level and Gil.

Level 60 version: Duty Roulette: HW Raids

All of the Level 50 version
Alexander- The Fist of the Father
Alexander- The Cuff of the Father
Alexander- The Arm of the Father
Alexander- The Burden of the Father

Rewards: Allagan Tomestones of Law, Allagna Tomestones of Esoterics and
a random Alexander Token, i.e.; Bolt, Pedal, Shaft, Spring, et cetera...

I think that this would be a great addition to the game and, would make veteran players more accessible.
