Weren't archers nerfed recently?
That said, I'm seeing archers being used a hell of a lot more than back in the days. I mean, those battles on EC are extremely archer heavy, barely any infantry when we consider everything. In Westgard we just annihilated a force of 20k rogues with 7k of archers (with a few ranged SF), we didn't even get a single hit on us either. Not a single melee unit in the army (there were 3 at the start of that campaign, though).
Seems like I've been noticing this trend elsewhere too. Westgard's kind of a special case because we only fight monsters, but elsewhere... doesn't feel right to see this. On EC seems like infantry's only role is to have 1 on each line so as to have the enemy waste a million arrows on a few men every round.
