Mercs are the only faction I know of that range camps. But then again, I didn't really get involved in many of the EU battles. Do all EU clans really have such a limited attack strategy?
Apparently you dont know crap about tactics either. Do you know what happens when an army with 200ping charges? Red is all you will see. (Red as in, your team dying)
Do you know what cav with 200ping vs cav with 60ping means? Red again.
And what happens when cav with 200ping tries to flank an army with 60ping? Some green and then just red.
What about ranged? Around 0.8-2:1 KD with 200ping.
You may counter this with "NA doesnt camp, herp" ... thing is they dont have all the archers to camp half of the battle... (Atleast I didnt count many in BRD battles...)
