I've looked and I see no mention of it. Sorry if this is in fact a repeat.
I just wanted to make it clear to my fellow Bloodsail Admirals (and Admirals to be) that you can still win the tournament if you are hated by the Cartel factions.
Riggle Bassbait, Jang and the Fishbot 5000 (along with Landro Longshot: the loot card guy) are still friendly to Goblin-hated characters.
Will it be harder? Yes. Definitely, because you may have a corpse run to do, which slows you down greatly. But it can (and has been done). There are a few strategies to employ.
1. BEFORE you start your Bloodsail Buccaneers grind, set your hearth to Booty Bay. This way, you can rez right in-front of Riggle. This is pretty impractical, but it is one method.
2. Have a healer on hand to heal you as you get whopped by the Goblins. This is still pretty roughshod, since dying is still a possibility (and also endangers your healer friend :P ), but with decent geared characters (or skillful), it is better than the first option.
3. Invisibility/Invulnerability potions and other alchemical boons. Still kind of dangerous, but if you practice maneuvering the city before hand, this is a very viable option. You just can't make a mistake or you're doomed.
4. This is the most effective method (and is what I used a few times). Have a warlock and two healers standby, next to Riggle and his buddies. As you make your 40 fish mark (or a few seconds before), call for a summon. When you pop, your friends will heal you and you can talk to Riggle for the win.
Death is very likely in all scenarios. But it can be done (at least prior to 2.4..., it hasn't been 2.4 tested YET. Testing this Sunday).
I hope this was helpful.
