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

As for the point that all units in the Conflux, except for the second-tier ones, are among the weakest. 1. For me personally, one of the main advantages of the Conflux is that the first two units have a speed of 7, which leads to a faster exploration of the territory in the early stages of the game. 2. As mentioned in one of the excellent posts by vam rad, the current meta focuses on powerful stacks. If you have three powerful stacks – wyverns, angels, phoenixes – that's already very strong. Plus, in case of a hidden unit, you might also have, say, air units. 3. With a hidden unit of psionicists, even if their upgrade is prohibited, and with GG Monere (by the way, his starting move is quite strong, perhaps the longest of the standard heroes), Psionic Elements can also become a powerful stack. Their stats in Monere's hands will be quite decent, and the number, even with just one external unit, will also be sufficient.
