Weak foot accuracy and usage should be reconsidered since the real effect these stats have in the game is not that noticeable and is more favored on the stronger side (players' weak foots are too accurate and used too often inside the scale). I've been forced to decrease accuracy and usage by 2 points for 99% of players.
I must admit that I miss the past 1-8 scale, despite of it not working to perfection. This is an idea with a proposed scale of six instead of four, and with a real/noticeable impact in the game alongside a realistic distribution, could provide a more realistic reflection of real life:
Weak Foot Accuracy
6 0.1% of players in the database (Only people named Cazorla, Adriano Correia, Pedro, Hernanes, Falcao, Maldini, Iuliano, Brehme, Kolyvanov, Sneijder, Forlán, Solskjaer, fit here. People who are as accurate as with their strong foot. 99.9% of them are right footed.
5 0.9% of players in the database (Only people named Neymar, Lallana, Kroos, Hazard, Modric, Ibrahimovic, Ribery, Villa, van Basten, Son Heung-Ming, Ronaldo, Nicolás Olivera, Moravcik, Zidane, Zambrotta, Sergi Barjuan, Nedved, Ginola, etc. fit here.)
4 14% of players in the database (Only people named Azpilicueta, Kallstrom, Lahm, Xabi Alonso,Totti, Figo, Matthaus, etc. fit here. A rare breed of GK in the mold of Ronald Waterreus fits here too.)
3 60% of players in the database (Default accuracy for most right footed players who play from the midfield and up, and lefties who are more than capable with their weak foot like Messi, van Persie, Ozil, Silva, Ryan Giggs. Other players like John Tery, Neuer and van der Sar could fit here too.)
2 24% of players in the database (Default accuracy for most GK's, most CB's/SB's and for most left footed players unless named Messi, van Persie, Sergi Barjuan, Giggs, Kallstrom, etc. Some righties such as Quaresma, Beckham, Verón may fit here too)
1 1% of players in the database (Only people named Čech, Robben, Bale, Ryan Babel, Antonio Valencia, Di María, Shaw, Moutinho, Maradona, Rivaldo, etc. fit here)
Weak Foot Usage
6 Same corresponding list as above. People who can actually switch foot at will for set pieces and be as accurate with their weak foot. They can transform into opposite footed players whenever they want too.
5 Same corresponding list as above, including some players with WFA 6 and WFA 4
4 Same corresponding list as above, including some players with WFA 5 and WFA
3 Most right footed players in the database who play from midfield and up, including players who highly favor their strong foot despite having a very good weak foot such as C. Ronaldo, Robert Pires, van Nistelrooij. Lefties such as van Persie and Ryan Giggs, Kallstrom could fit here. CB's who use their weak foot a lot like John Terry fit here too.
2 Default usage for most right footed players who play from the midfield and down (with WFA 2) and for most left footed players (including many lefties with WFA 3/4) unless named van Persie, Sergi Barjuan, Giggs, Kallstrom, etc.
1 Most players with WFA 1/WFA 2, and some with WFA 3/WFA 4. Same list as above, including some players with WFA 2 and WFA 3.
On another note, and I've been asking this forever, I would like to see a button combination to switch foot (and have the AI opponent switch foot if appropriate) for the main set piece taker (penalties, corners, free kicks). This should only be available for players with weak foot accuracy 5 and 6 in my proposal.
Another option is for these players to have their preferred foot options branched out. Having a default preferred foot for fk's, corners and penalty kicks.
For Example:
Preferred foot Options: right, left or both (switches foot automatically depending on the side of the pitch and at the press of a button for manual liking).
Anderson Hernanes:
Preferred Foot:Right
Weak foot accuracy:6
Weak foot frequency:6
FK foot:Both (have the option to switch foot with a button combination & AI if controlled by CPU)
CK foot:Both (have the option to switch foot with a button combination & AI if controlled by CPU)
PK foot:Both (have the option to switch foot with a button combination & AI if controlled by CPU)
Paolo Maldini:
Preferred Foot:Right
Weak foot accuracy:6
Weak foot frequency:6
FK foot:Left
CK foot:Both (have the option to switch foot with a button combination & AI if controlled by CPU)
PK foot:Both (have the option to switch foot with a button combination & AI if controlled by CPU)
Hernanes can take set pieces with both feet at will when he choses too, Diego Forlán still switches foot for set pieces outside and inside the area in Hong Kong. Andreas Brehme used to switch foot for taking penalties at will, Wesley Sneijder used to switch foot at will for free Kicks and corner kicks when younger, Paolo Maldini, despite being right footed, chose his left foot for kicking set pieces and making long passes. Nicolas Olivera (ex Uruguayan international) plays with his left foot but kicks penalties with his right foot.
