Necropolis or Castle (Which one is stronger?)

Experience shows that Necromancers are stronger than humans. Much depends on the players and the map, of course. But if the start is approximately equal, then humans have little chance (diplomacy can help, but there aren't always worthy troops to join, and time is of the essence). The Necromancer starts strong: the initial hero's skeletons + 2 heroes in the tavern (whose troops will also become skeletons ;-) ) and in the first week we have about 100 skeletons, we can develop and level up... You can play against Necromancers using the Conflux, and sometimes the Rampart; this is my personal opinion, but the best strategy is skeletons against skeletons, and then everything depends on the player's skill (and luck – that is, the map ;-)).
