Just to be the contrary voice from the wilderness, you can easily RoA without any support at all.
If you have no competition for the quest spawns and the server and network is cooperating then it takes about 9 hours for a 1.0 epic toon in potimea gear to complete an RoA cycle with no support beyond the buff bot. The secret is to grind the quests(1) and to take a moments pause in (Dulak / Fear / Fire) between your last Dulak turn in and beginning the Velks line. (The Frell Shagwell Velketor's Lab quest line is acquireable at 50 but is not very easy to do before level 53-54 for most classses. A short pause for non-quest leveling is in order here for overall speed in the process.)
Been there, done that. 16 times so far on Soloista.
Eminently doable, it just takes for-EVAH!

(1) By 'grind the quests' I mean acquire the quests in SFG, go complete the requirements, gate back to SFG to turn in immediately upon completion and then repeat the process. If you happen to end up a kill or two off level go ahead and level, but generally speaking you want to head back to repeat immediately. The big exception to this practice is for those places where a quest ends and you move to a new npc for tasks, like when Field of Bones is offered the final time at level 10. Then you should go ahead and level to 11 after completing the requirements before turning in.
