Tactics for Conflux.

I always face a dilemma at the beginning of the game: who to choose: Gaaltran, Vidomina/Isra, or Tant. According to my calculations, skeletons of the first level deal about 20% more damage compared to a hero without any specialization. Isra/Vidomina raise about 20% more skeletons, which is basically equivalent. (in the calculations, I assumed level=10) That leaves Tant, who is very useful because I always have losses in battles, and I can't do without resurrection. Most often, at the start, I choose Gaaltran (because the specialization is useful). Then I try to get Vidomina/Tant/Isra and give them vampires, and in the following week, I build up cavalry/liches and give them to the third Necromancer. The main problem against Conflux, when we play, is that vampires do not regenerate from elements. As for skeletons, it's 50/50. If I'm lucky enough to learn teleport and throw them into his castle, then everything is fine, but if not, he brazenly shoots me from behind the walls.
