Tactics for playing against a Necromancer.

We're no longer talking about rushing, since we've moved to the end of the first month of the game:p

So, are battles considered rushing only if they happen before the end of the first month?

Necropolis is still the best rushing faction in the game;

I completely disagree. A Dark Elf, leveled up to 15-16, seems to me, will leave no stone unturned for Kaspar and other Necromancers by the end of the first month.
