I have to spread some more XP around before I can give you some, but this was awesome. You are right; we are like spoiled children when the topic of "what D&D means to me" comes up.Funny... I immediately had an answer in my head when I saw the thread title, which was The Biggest Issue In 5E. Then when I opened the thread up and saw the poll's actual request was The Biggest Issue In 5E Design, I realized that my answer wouldn't actually apply.
Cause my original answer was that the biggest issue of 5E was going to be the incessant caterwauling of some players who discover that 5E won't actually play in exactly the same tight, restrictive, inflexible, 'this is what D&D is to me and I have to play in this specific fashion and I refuse to compromise' way that they want. And they are going to spend years bemoaning this fact, especially claiming that WotC lied to them said from the beginning that they were "going to make a game that was all-inclusive, but which they failed miserably at and most certainly did not!"
And the rest of us will have to listen to it for years.![]()
I voted for "Combat Speed", because that is by far my biggest issue with 4e.
What sort of "baggage" did you have in mind? If you dig deep enough, even halflings could be considered "baggage" by some players...Previous Edition Baggage. Everything is important, but make or break on 5e is this. I'm trying to be optimistic for them, but its going to take a helluva marketing campaign (open playtest is a good start) to make this fly.
