hey tff, mate, would you say its 50% the players and 50 % the tactic?
Mate, I'd say your results depend on the quality of your players/their suitability for your tactic and the quality of your tactic.
Which of these factors contributes more is not important at all and the only what’s important is your understating that all these factors contributes.
Also your result depends on the competitiveness of the league you play.
For example, when I pick the weakest team in Sky Bet Championship and make 4-5 transfers(I have the first transfer windows budget – ON) then I'm able easily win the league with this tactic but when I pick the weakest team in English Premier League then it's very hard to win the league in the 1st season and usually I end up in Top 3, of course, I also have the first transfer windows budget – ON and without rebuilding the result would be even poorer.
Any plans to create a tactic for lower leagues?
Mate, in order to do well in lower leagues you don't need any "special" tactic for lower leagues and further more it's much easy to overachieve in any low reputation league with any tactic than in any high reputation league with the same tactic due to poor AI intelligence in low reputations leagues that now allows it using the weakness in your tactic.
but was asking for advice.
Here's my advice to you: learn how to rebuild your team to suite the tactic, this includes:
1) Look at your team and find out what players might be used in the tactic and what players should be sold.
2) Sell players that don't suite the tactic. For example, you have 5 strikers that can play only at STC position so you don't need that much for this tactic and having only 3 strikers would be enough, so sell 2 excessive strikers.
3) Buy/Loan players to strengthen the positions where you see lack of players. Bear in mind that you need at least 2 players for every position and the optimal is having 3 players for every position because there’ll always be injures/suspensions/tiredness during season.
4) Find players in your team that require only slight "re-training" to be useful to the tactic. For example, you have a player with good attributes to play ML position in this tactic but he's got only "Unconvincing" rating for ML position so it isn't necessary to sell and you can easily train him to ML position because it shouldn't take longer than 1 month for him to get at least "Competent/Accomplished" rating for ML position if you set him train this position.
5) Learn to pick the best quality and suitability players from players that available to you. There are recommend attributes for each position in the tactic. Look at it and learn what kind of players you need for the tactic and which attributes are important for every position.
