Pride of the Legion requires a revamped Droga, the npc doesn't exist in the current p99 version of the zone.
I don't have any patch notes to prove it, but I think the farthest one that would be doable on p99 would be the 4th - Trooper's Pike or possibly 5th - Legionnaire's Mancatcher.

I don't think the Bloodgill Goblin Scavengers are spawning for the 6th pike/mancatcher quest since I didn't see them in a few days of hunting bloodgills. I'm also not sure if the Goblin/Sarnak Messengers are spawning in LOIO, WW, FM, and OT (also for 6th).
I had an iksar warrior alt during PoP and I remember their quests being well behind the monk/sk ones at the time.
