I must say that I've noticed this as well. Most tactics I've seen in the game now revolve around heavy use of archers and ranged special forces, with token melee units used to the fore to hold up the advance of the massed ranks of ranged forces.
However, it should be noted that all melee forces are almost entirely useless against the massed monsters on Dwilight, so this compels armies to use ranged forces against them. Any rebalance of ranged units should take in to account the peculiarities of Dwilight, or we'll have a lot of deeply frustrated players if the monsters suddenly become almost unbeatable.
