I think I need to expand on my own post here. It got to a point where other players felt useless in combat and it became a problem. It was an issue for the DM to build encounters because something my character could walk through was a overpowering threat to everyone else. So every primary threat needed to attack only my character to the point it became clear in combat there was just some extra enemies thrown in who would fight with the rest of the party.I think the main thought behind what folks were saying (myself included) is that a5e is harder to create a truly just damaged focused build but that where you used to have to sacrifice all abilities outside of combat, you can still build to be effective in combat but your still going to be useful elsewhere.
And to be fair last campaign I was a player was a 3.5 campaign and built a character so effective in combat other players felt they didn't need to do anything.
I can see this happening with o5e. I can't see it happening in a5e
