Sylvan vs. Necropolis

Regarding artifacts, of course, 2 rings and a staff are better than one ring; the bonus will be higher, but the initiative won't be increased by 50%, but less! There's a more complex formula involved, something related to multiplication. But still, Winghael isn't designed for taking castles; I usually rely heavily on Blade Dancers and Unicorns. Besides, towers are unpleasant. Regarding Druids, the Elder Channel is still considered overpowered, right? It's true that Specters are a problem.
