Hi,
Turtle made plenty of quests for Bloodsail Buccaneers. They are useful for levelling from 38 to 50 and just for being unique and cool in general.
There are a couple of things that could easily make them feel more complete though.
Two things specifically:
1: Vil'do One-Tusk actually does teleport you to Feralas.
Currently, there is a dialogue option with this NPC saying "Let's set sail for Feralas!" which does nothing. It is clear that Turtle intended this to be a way to travel for friends of the bloodsail as an alternative to the BB way.
I suggest adding the exact same ship with the exact same NPCs in Feralas. The only difference there should be that Vil'do's dialogue would instead send you back to Jaguero Isle in Stranglethorn. The location of the ship should be non-interfering and forcing some swimming to get to the shore - some way off of Sardor Island (Feathermoon Stronghold), perhaps to the northwest. I have to stress that the transport would be a teleport, not involve any actual movement of the ship.
With this addition, Bloodsail would become useful as a faction to be allied with, but nothing overpowered.
2: Make lvl 55 or maybe 60 versions of the reputation gear
This addition is very small, but would simply mean making a higher level version of the hats and coat at lvl 55 or 60 as you decide. By no means should these be super strong, but pretty good as preraid items.
By adding these two rather small changes, especially the first one, the Bloodsail would become a much better and more fun faction - building on what Turtle had already spent a lot of work doing. It would be really awesome if you would add this!
