I wouldn't mind something like this perhaps with it on DLC like say a pirates Cove, Where the ship people are asking for is actually a House that is docked. Or you could use the cove of the ship as your dwelling, would add nicely to RPing. Secondly a pure thieving class I would throw money at. Love the idea of Breaking into places and using stealth tactics to which I find could be developed a little more in this game. Yes thieves guild line was ok. But I would love a pure thieving class that doesn't base Every mission around combat. More a sly Jack Sparrow who can use cunning to get out of a bad situation...
EDIT: Also From looking at past unbelievable housing designs in this game a massive Pirate Ship and Hideout would be something I would really spend a ton of the $$ on haha
So while deep down I feel this is not a fit for ESO and don't think this is in anyone's plans... I would still love it and be so psyched. I love pirates. I don't even care that we can't swim or have moving boats. I would be into it very much.
My #1 wish for ESO Today: Decouple achievements from character progress and tracking.
