people should just stop saying "this or this tactic is the best". I think you can see where a tactic is actually quality. Rock is high quality, Arrigo Sacchi is also quality, modern warfare was quality if we look at people's results (even if I never tested it). There is such a huge RGN in that game that you could save/load a game 20 times and get very different stats.
I just hate when people come in a trade, claiming than something else is better without any reason but because it had better results for them.
I'm not even sure there is a real way to really compare 2 different tactics. Maybe a huge sample like playing 10 times the 1st season with a tactic, then doing the same with the other tactic, and see what's giving better results in average.
I also noticed that some tactics may not work as well in some championships. For example, the 4-2-3-1 is something standard in Bundesliga, while something like narrow 4-2-2-2 or 3-3-2-2 is standard in Brazilian league.
Anyway, the rock tactic is a good one. Probably not the best for everyone, but for most it seems to be the 13.3.3 leader.
