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

Conflux is good in many ways, except for one: weak units.

I disagree! Take a look at levels 2-3... Archers are amazing! Level 2 is like level 3, level 3 is like level 4... in terms of stats... So, don't talk about weakness! Upgraded fairies are monsters! (because of their retaliatory strike and quantity). And so on... plus immunities to various magic... In general, their only downside is that they are expensive in terms of gold.

P.S. I don't like playing as Conflux :)
