Wait, so a unit of zombies- *zombies*- joined by a captain can end up with WS4, depending on the champion? And a similar score for Initiative. And a BS of 3- as good as a living archer. Are these Elven zombies? I think the balance of zombie and pirate is beginning to waver a bit, more in the favour of pirate.
Also, aren't the Infamous Alias' (and the limited "Vampire" Powers, if we use them) going to be enough for the Zombie Captain? Do they need to add such a significant bonus to the units they join? After all, this isn't an official list, and you'd need to get an opponents permission to use it. If I saw home-brew rules like Watchful Eye, I'd have my opponent agree not to use it before agreeing to a game. It doesn't have any background justification and is mechanically unsound.
Also, sorry for the double postr, but I've had an idea for a special character:
"Jolly" Hrethgir
In life, Hrethgir was a Norse raider sworn to the Blood God and renowned for his lack of humour. When Hrethgir plundered a pair of enchanted Warplock pistols from a Skaven slave hulk, he was instantly overjoyed by the killing power of the pistols. He started wading into battle, a pistol in each hand and a maniacal grin across his face. However, the Lord of Skulls was displeased with his champion not only using ranged weapons but magical ones at that. When Morrslieb waxed full and pulled the Blood Tides in, the Brazen God sent a hellish galley crewed by Bloodletters to board Hrethgir's long-ship. The Herald Captain ran Hrethgir through and tossed his pistols into the sea, their Warpstone mechanisms fizzing in the brine. Then it lifted Hrethgir high above it's head and said:
"Keep on smiling, Hrethgir. For you are cursed to sail the seas until the end of days and to walk the earth only to spill blood!" The daemon then threw Hrethgir into the depths. But true death was not to find Jolly Hrethgir, for although the fish and gulls cleaned the flesh from his bones, he was still driven by the joy of battle and the bark of his cursed pistols.
Essentially, a Wight with a brace of pistols that count as a magical attack. Maybe with Killing Blow (because he's a Wight and a good shot.)
