I use Shield Wall V10 away from home in the championship and I am unbeaten with a team predicted to finish mid table.
What I would say is that I have had extreme success home and away with Gladiator and Conqueror prior to my recent club switch, but I was always a slightly better team predicted perhaps 2/3/4 finishing position in whichever league I went to.
Now, I played my first few away games with Gladiator and got beat, often with stats like 25 (me) shots to 4 (them) (losing 2/3-0). The only thing I could do was stop them shooting, and Shield Wall does that perfectly. I then win 1/2-0.
