I had this conversation with a friend of mind playing a centaur in another D&D game:
Me: A centaur? I guess that campaign won't be spending much time in dungeons or climbing mountains?
Him: Huh?
Me: Centaurs are large and awkward creatures. Just going up and down stairs, ladders, doorways, anywhere the party might need to crawl, turning around in very narrow passages, all of that is going to be a recurring obstacle. So I am assuming the game will be a more pastoral vibe.
Him: Centaurs are medium in 5E and you can worry about that stuff or you can just, you know, handwave it
and have fun.
Me: Handwaving that stuff is the opposite of fun to me.
So that's where I still stand, but I'm glad some folks will have the options for their own style of game.
