so I've been playing MP and tend to hold my own(many times even in the top 3) until it's times for the semingly inevitable war. The opponent usually comes in with swordsman and catapults. Everytime I shoot the swords he just swaps them on with a new unit and often the old unit has a promotion. I rarely ever take out the unit I just damage them, the get swapped and promoted. Being that I play on WIFI with a upload of 15mbps and a download of 2mbps I might just be having lag. So I get these strong armies and get wiped out really quickly. Is there a good combat guide I could look at?
