#5 he means that if the attack misses in BG3, you have Larian cheese to still ensure you can be effective that turn.
You use your full action to make a failed attack or spell, you can still potentially shove someone with a bonus action for maybe even more than the attack.
You shoot an elemental arrow and miss? Well, you still create a surface and generate some damage.
Abusing the environment is one way to put it and that is why Larian is balancing towards players with this mindset. They fear too many people will get frustrated with 5e and missing whole adding nothing for numerous turns in a row.
