- Which faction is stronger? (Necropolis, Tower, or Conflux)

Regarding Necropolis. At the beginning of the game, it's quite challenging because the first (and last) ranged unit is only available at level five, which creates difficulties. Tower, on the other hand, is the city with the most ranged units. And although many say that it's difficult to start with Tower, I still believe that the Master Archers are very helpful in the first two weeks.
Conflux is good in many ways, except for one: weak units.
