Like lots of things the truth is somewhere in the middle and a hell of a lot more nuanced. Jookie's post last night (I think) which highlighted what we've actually done since 2006 is a good case in point. Seeing the wider context does not necessarily mean indifference to the FA Cup.
I'm not sure many people were arguing that we had a squad that could compete for 3-4 competitions when our recent history has shown us falling short when chasing one cup, let alone multiple trophies. League in 14, Europa in 16, and last year were all examples of a thin squad, short on options falling short. The squad is in better shape and improving, but unless we are very lucky with injuries we are not there yet.
We may have more numbers, but there are form issues, compatibility issues and fitness issues. Henderson, Milner, Shaqiri, current form Kieta are examples of players that add depth to the squad and are of the right quality as well as being able to fit the system. On the other hand players like Clyne, Origi, Sturridge, Lallana, Mignolet, Moreno are either not good enough, not reliable enough, not compatible or in some cases all 3. Those 6 players alone are taking up significant wages which could be used for players that offer more. That doesn't mean Sturridge cannot do the odd 20 while he's still here, or we can't chuck Origi on for the last 10 in an emergency, but longer term we need more from those squad places.
Despite the rotation, arguably the intention was for the team to have been stronger last night. Last year it was midfield injuries, this time it's defence, and that coincided with the need to give Van Dijk a break. Added to that is our abject luck with draws over the last couple of seasons which has hardly helped matters when it comes to gaining a foothold in a competition whilst also resting players. City and Chelsea do seem to get regular home draws v lower division opposition don't they?
I love cup finals and have had some great times at them and am sympathetic with some of the views, but it is not as simple as saying that we exist to win trophies. The league is tougher to win than ever before, when you are looking towards 95 points, that places a completely different perspective on planning a league season than simply being less inconsistent than everyone else and walking away with a title with 78 points. Under Klopp had we lifted the league Cup and FA Cup, but perhaps not reached European finals or qualified for the CL twice, it would not be difficult to guess the refrain wold it?
"Salah needs to be in the Champions League" "Mane needs to see he can compete for the top trophies" Do we attract Allison and Van Dijk with our 2016 league Cup?
This is Klopp's third full season; in his second we reached the European Cup Final, this season we are in a title challenge. This is on top of a bonus Europa Final and back to back top 4 finishes. We are now competing for the top trophies. The squad is better, but not there yet. If the 6 players mentioned above are replace with say 4 that can comfortably be interchanged with the "first" 11 without weakening it and then supplemented with some Trent quality youngsters, we may even be able to compete for 3 trophies next year, but as a fanbase we've got to stop over reacting to the slightest thing, appreciate how far we've come and understand how the competitive environment around us has changed since the times when we used to win everything every year.
