In PLA, catching pokemon was the focus, even without having to battle
To that end there was free ball throwing, throwable items with a crafting system, and a stealth system, that you could apply strategically to sneak attack capture any pokemon in the game's open wilderness that had them moving around and interacting in a way that vaguely approached what passes for a realistic ecology on gamefreak's poverty budget
ZA wants you to just be fighting, so removed the throwable items, dumbed ball throwing down to just using your lock-on, gives you a chance to catch a fainted pokemon, prevents you from throwing more than a couple balls, and places you in severely cramped areas with not much opportunity for stealth that has you often fighting off entire groups of 2-8 pokemon all at once
Also I'm not sure if they dumbed down catch chance, but now it shows you a meter of between one and four pips that represent it, which seems incredibly streamlined given everything that should contribute to it
Some of those changes were necessary to stop stealth spamming from being so broken, but now you basically don't do it at all outside of the early game. You can now sneak attack with your pokemon which would retain some of the use against harder to catch pokemon, but that only really gives you a tangible benefit against trainers
