trying to blame a fantasy game for a "lack of realism" is really a lame excuse. The reason for liking or not liking a game is a person's bias, period.
And if your bias is toward a "greater degree of realism", then you won't be satisfied by the game.
Anyone claiming the WotC needs to "bring back" versimilitude or "realism" is utterly wrong and quite frankly directly insulting EVERYONE who likes the other thing.
If you're happy suspending different parts of disbelief, or more disbelief, good on you. Not all of us are. And 5e is supposed to be appealing to a wider audience, IE the people who weren't satisfied with 4e.
Breaking my sense of verisimilitude in too many large ways is the main reason I don't enjoy 4e. Judging by the replies, I'm not the only one bothered by it.
And where I want a higher degree of verisimilitude to well written fantasy fiction and (in a way, to the real world*), then if the main rules are filled with daily and encounter abilities, I wont have much interest in buying into the modular parts will I.
There are things you like, there are things I like, but claiming either is "more realistic" than the other is pure bias and is in no way, shape or form objective. It's passive-aggresive, self-righteous edition warring, nothing more.
More realistic is hardly an issue of bias. I suppose you could say "more realistic towards what", if you're not using the real world as your measuring stick.
So More Realistic, in this sense could either be "better modeling reality" or "Breaking your sense of verisimilitude less".
In my case I mean a bit of both. "Better modeling reality - (while maintaining playability)" is my minimum starting point, before you start adding on the fantasy elements.
Breaking my sense of verisimilitude in large ways is how to pull me out of immersion from the game, and how to stop me from enjoying it.
Many of us won't be interested in 5e if it doesn't manage a great deal more verisimilitude than 4e managed. Like it or not, we are a part of the 5e target demographic.
