Game Mechanics: Melee PvP on boats, but no spell casting!

[Softcore PK]

I say let melee continue working on boats. Melee classes waiting below deck is very much classic and was almost never a huge problem (exceptions for RZ item loot, I'm sure). Every caster class but cleric receives the see invis spell, and clerics have the defense and weapon skills to put up something of a fight with just melee, anyway. Especially buffed. In most cases, dying to hidden rogues below deck will be because the proper precautions were not taken. This is not true for casters that don't have seen invis, but at those levels casters generally dominate the melee (naked wiz > naked rogue) everywhere else.

The idea of safe areas really bothers me, even if it is just on boats. I'll be going druid or cleric on live, btw :P
