The strength of Necro lies in the huge number of raised skeletons + the converter: scout heroes, external dwellings, zombies, maybe wraiths, secondary skills.
Blue Necro (if spawned in the Dungeon) can certainly be a pain, especially if blocked by shooter guards.
I didn't have 500-600 skeletons by the second week (123-124). That's closer to the third week. But even so, a mediocre player like me sometimes cracked Dragon Utopias of the triple on the second.
My opinion: (for SM at least) Necro is most vulnerable on the second week. That's why you need to rush them right away (magic, archers, maybe Angel) — starting from 117.
If you didn't kill them by the second, then that's it! GG.
All IMHO.
PS: Regarding the argument, VLK offered to play Vika, let the match decide for you :smile02: up to 3 or 5 wins.
