I have almost 99% the same mentality and instructions like you. Wide works ok for me, the only problem is my Wingers are being nerfed in speed terms usually. When the CPU AI lets them play according to their stats, they are ok. I am a wing/side player in every pes i think.
Now about short pass, i have short pass too, cause in long passing, i do not trust my player's long passing ability. But i think , cause i have player support on 5, it does not work as it should to. On the other hand messing with player support, i don't remember now if it works as it is displayed on gameplan sheet, or inverted, tends to make player be to close the one to the other, abandoning their original positions, or being two players in the same square and leaving the field without movement, or having it to be distant each other, and it denies the purpose of short passing.
Import to the equitation of all the above and the advanced tactics, like gegenpress or tiki-taka and you take a complete madness!!
