Ok aince my previous post was deleted cuz off topic since i could not answer but asylan was right. i was too busy i will tell u ezactly why you should attack woth just 1 unit every turn is bad.
first off the fact that u are only letting 1 unit die everyturn doesnt sound bad but in the long run that adds up to 8+ units WHICH IS A BIG DIFFERENCE IN UNIT COUNT OVERALL espexially during west duels.
second, dont be an idiot and sent the bare minimum when there is 2+ units wfing ur cap. send twice as many sometimes i sent theee times as many to kill the wfing unit because of the stack bonus which makes me lose less unit count
third, letting 1 unit wf all game is stupid. u can just let ur cap be open with 1 unit all game. being able to wall ur cap and not defend it every turn makes a huge difference. u can ask any comp player and theybwill say the same.
SO KILL THAT WF UNIT IF YOU WANT TO WIN.
