Which faction poses the greatest challenge for the Dwarves?

Dwarves are a very strong race, but they have their drawbacks. In my opinion, you need to eliminate the priests and spear throwers as quickly as possible (if you're playing against Dwarves, of course). If not against Dwarves, then eliminate the Jarls/Earls. A good tactic is to "cast spells and run away" (Sanitarius's favorite method). The main problem for Dwarves, I think, is Mages with their summons, especially fire traps, elementals, shield, and phoenix (the chance of a Dwarf summoning is 4%, and I don't think they'll take Exorcism). The Mage should take Light and Summoning, 100%, and take artifacts for initiative. Dwarves start well under Ingvar and against Dwarves.

P.S. You can tell me which hero you'll be using, and then I can say more…
