Holy crap yes, strong agree. And I think if diving slip catches were possible that would blow my mind. I'd stand there for a full innings for a few good chances.
It's not going to happen, though. Would prob eat up a load of dev time and only add value for single player fielding.

hmm, although I guess it depends on how jarring flipping from bowler to first person fielder would be.
I can't imagine a lot of players would want to flip into first person mid delivery.
One way I think fielding would be improved is thinking about grouping what you are able to do into close fielding (slips, keeper, around the bat, return catches), inner ring fielding and outfielders.
For close fielding I think a mild slowing of the action with a XYAB above possible catchers (including keeper). You trigger which one you want to go for the catch. I think this would work better than the current mini-game (it's one of the reasons I use fully auto fielding at the moment). If you've seen the glory kills in Doom I'd imagine it working in a similar way. You essentially trigger an animation but the flow of the game is hardly interrupted. Something like that could perhaps incorporate variation to catches, dives, drops.
Something similar for outfielders, with the XYAB selection determining how you attempt to gather the ball. Depending on fielding ability of the player in question might mean some try a slide and gather and end up looking like fools. Likewise you might be able to choose between triggering a player to attempt a safer jumping tap back or a riskier tap back catch. I like the simplicity of being able to do something spectacular with the minimum possible input. When the ball is in hand a PUBG style mechanic would be great.
For inner ring fielders, mostly thinking those in your Mid On, Deep Mid On distance, I'd put Short Mid Ons in the close bracket. A balance of the two. I do feel like a system that prevents the game from being slowed down, unless absolutely necessary, is the best way to go. So for a catch there is keeping the default camera, like for close fielding but with ball in hand you are able to control the throwing action.
It might not necessarily be something that enhances test matches but in the shorter formats, where all round fielding is a key component, it could really add some enjoyment were the fielding a bit more dynamic.
In terms of switching the POV I think it has to be as smooth as a camera angle switch. Maybe an option for first-person or third-person over the shoulder could at least mean that those not interested in a first person switch could choose.
