Discussion about Sylvan (Wood Elves).

.....so many very unpleasant spells of Dark magic appear (Suggestion, Berserk, Blind, and mass slowing, weakening, and poisoning spells, etc.)

Which appear in the middle or towards the end of the game. So, in any case, Elves cannot be allowed to gain an advantage, considering that they don't gather many resources at the beginning. For Elves against Necropolis, a rush is a wonderful strategy.
