How do you use Conqueror at home and Shield Wall away? I also ran Real Sociedad and tactics, which in my opinion was the best, but after updates it spoiled. 19.2
I don't use different tactics for home and away. I usually start with Conqueror tactic and change to Shield Wall if I'm not happy with the play or result. Against bigger teams I start with Shield Wall. For now this seems to be working for me on the last patch 19.3.5, but maybe because it's the first season of a new save.
