By playing c-RPG? How're you going to magically stop ten thousand archers from spreading out?
archers going rambo on flanks can be taken out by cav, and even if they are dodging and somehow playing rambo and not dying they should be too focused on dodging cav to be firing at flanks. In village maps archers have an easier time but in this case they have outmanoeuvred you and your team hasnt responded correctly (which is fine) it just means you are getting flanked which is part of the game. In this case its a matter of not having a plan and responding to a threat that maybe someone should have called out.
I dont wanna go through every scenario but basically it either comes down to your team not responding to archers roaming about getting free shots, or your team has just been defeated through solid tactics and now you have to somehow convince your pubbie team to also come up with a plan
But really if you have 3 archers firing at you and its not the end of the map, then your team is majorly screwing up somewhere (I suspect cavalry) and if you are losing out because of it then maybe you should sort them out with a real plan
