I don't think table of counter formations work that well myself, probably around 70% success rate or something I'd imagine. It's not reliable and everyone should play the game on how they should play it more than anything else.
Of course the table of counter formations is there for anyone that wants to use it and believe in countering still works.
Another thing... I'm tired of seeing posting for formations help in General Chat and should only be posting in Formations and Tactics. After all... That's what Formations and Tactics are for and anyone that likes to give out their advice will sooner rather than later will post a reply.
Honestly, I don't know what so many forum members keep approaching me for advice on "How to beat this formation" when I actually dislike giving out such advice. I come here to try and make playing T11 quite creative and make loads of match reports and progress on the game more than anything else. If it wasn't for this creativity and the PvP experience of T11 I'd be playing Football Manager instead. The best examples of such creativity have came from leddy and zJordan in the leddy fc news post.
