So, archers should stand in an open field where cav, other archers, and godzilla for all I care can rape them at leisure? Um, no. Buildings only deter the hardest counter for archers, cav. It's not OP, it's rock, paper, scissors, balance. If there's a building with 100 archers crammed in it and you can't assault (cause you're a useless cav in a city map), you pull a trick out of Nord Assault. Wait for the flag. GG.
Hey, or you could bring a 1h and get off the damn pony.
Next, well see a guy complaining at length why shields are so OP because they can just walk right up to him and slaughter him in that ruined building. Again.
