I agree! There are limits to it all, but its up to you as a dm to make it fun for everyone and letting players flex is included in it! I have a lvl 5 paladin the dm has huge issues hitting and its hilarious sometimes! That said, i cant hit for shit so this makes it fun for the dm as well. My team mates have once just looked at me and the last skeleton warrior duke it out while the rest was dead. It couldnt hit me and i was constantly missing my attacks. We were all laughing our arses off haha
