I would suggest taking a look at the TT&F thread (link in the Bible).
You're right that it is more difficult to balance things away. Sometimes a little too difficult. Unfortunately, there's not always a quick fix.
You have the right idea in playing more attacking, I think, but it's a question of getting the balance right between attack and defence.
The tactics created from the TT&F frameworks usually contain a number of variants. The home one is usually pretty much static (though sometimes there may be an overload version where the mentality is even higher), but the away sets contain more subtle changes. There is a normal away tactic which is very defensive. Then there will usually be an attacking away tactic which is five or six notches higher and finally a very attacking away/defensive home tactic which is between the away attack and normal home tactics.
With my current Arsenal game, as an example, I have three basic frameworks. One is a home variant, quite attacking, wider than normal and designed to march forward. A deeper defensive line watches for counter attacks, but basically I leave this baby alone for home games. Usually it will win.
Away from home I have two separate tactics. Both were built with defense in mind - narrow, lower forward runs, deep defensive line etc. However, one system has a RoO framework starting a "1" the other starting at "7". For games where the opposition want to win, the "A1" system works a treat. However, if the opposition sit back too much I switch to "A7". Finally, if that doesn't work, I've been know to switch up to 13 or 14 or even just crank out the home tactic and try and force the issue.
I hope that helps. If it's any consolation, you're not alone. I dropped 9 points at home last year. But check out the table...
Doing better this season, just about, but it's bloody annoying, eh?
