Felia Goldenwing and that spawn cycle in SF

[syztem]

So I have been interested in this mob fora while, as well as the cycle for the named mobs themselves for immortal books. I can't really find any concrete guide on spawning her, Some say just kill mobs around druid evac and infront of BW/SF zone line and keep a eye on track for the named mobs. in an old post by gms these mobs were listed as the ones to kill to respawn them or the nameds.

Skyfire_Special1 (Spawngroup id: 1507) 30 second respawn
Skyfire_Special2 (Spawngroup id: 1508) 60 second respawn
Guardian of Felia (91005) [44] = 5%
Faerie of Dismay (91012) [47] = 5%
a wandering wurm (2186, 2187, 91031, 91083) [47-50] = 2%, 2%, 2%, 2%
a shadow drake (91063) [47] = 5%
Felia Goldenwing (91081) [45] = 2%
Black Scar (91088) [45] = 5%
a lava walker (2190) [52] = 5%
a wurm spirit (2208) [47] = 5%
a soul devourer (2207) [46] = 5%
a bottomless feaster (2183) [46] = 11%
a skycinder drake (91006) [47] = 11%
a mature wyvern (91003) [48] = 11%
a mature chromodrac (91052) [49] = 11%
a mature wurm (91053) [47] = 11%

Felia obvious is pretty low spawn chance I see, I saw on blue whiles back people selling spawn loot rights to felia. I have followed leads saying to use a bard with highsun, in order to highsun all the mobs in the BW/SF area back to bind with someone sitting near the spawn point near OT where the named/ph originally spawn and path from based of this guide for bards:

[You must be logged in to view images. Log in or Register.]
After spawning, Eldrig wanders west and follows the pathing shown. 559 -4003 is where PH spawns. Won't roam back to spawn location. Good strategy to find the correct spawn is to have 1) 1 person at 559 -4003 2) have a bard start a train where it can roam 3) have a necro bracer the bard needing the piece near BW zoneline 4) bard zones 5) aggro switches to necro where he can rune 6) bard spams the song highsun mobs to warp the mob back to the spawn where it can then be camped (oleris)

I have never used highsun before, but it seems to fizzle like crazy, and require an almost melee-like distance to sing it on a npc. I can only assumethats why the guide is written as so that someone other then bard takes over aggro. So I look to others to help with any advice/info on doing this, before I just murder the entire zone and then login a ranger every 30 minutes to track the zone. If the highsun/PH theory is correct for felia then that means I must kill the mobs listed above, named and multi non-named included for best option to spawn named cycle.
