Why can't you just like my post like everybody else
No seriously, I totally get that and you're right, it does have a hell of a lot to do with confidence. But sometimes that confidence comes from swtiching things around and dropping certain players - that is what the manager is paid for after all.
I was only pointing out the positives in the change in formation, and to be honest I don't think any foresaw the drastic effect it had on us. For example who knew the Ox would take to RWB like a duck to water. I agree it's not the be and end all, but it bloody works and works well for us. Not many of the players changed in the line up, but we looked a much better team. We were so, so bad towards the last few games using 433, something needed to be done, glad it came late then never.
Anyway formations are always changing during the match, they are fluid. Formations are just a graphic sky sports like to use pre-match. 4-3-3 would be 4-2-3-1 when defending and basically 2-1-4-3 when attacking. For me it's more about the individual roles of a player on the pitch rather than formation. In the our latest formation, players seem to have more defined roles and know their job. When we played 4-3-3 we would often get countered to fuck at almost every opportunity.. I'm sure there are stats out there that show we've faced less shots since changing.
