Sword of Spirit
Legend
Oh I will agree the system as it was in 4e could have used refinement. I just like the philosophy and basic principles... and I'm just sad 5e didn't go for a proper refinement of the system instead of just reverting to some janky 3e call back.
Just to clarify, that's not what happened. To develop 5e the designers went back and played every edition of D&D (starting way back at OD&D I believe). They attempted to create a game that captured the best and most well-received parts of that decades long history of editions. D&D 5e is a sequel to D&D collectively, not to any particular edition. During the public playtest, they made many changes in different directions, which included adding new elements that resembled each edition, and subtracting other elements that resembled each edition. What we ended up with is what appealed most to the collective voice of over 100,000 fans of various editions. While it's basic structure probably sits somewhere between 2e and 3e, there are plenty of features that were inspired by 4e that made it in, such as at-will attacks, and even the usage of hit dice is inspired by healing surges. It's also worth noting that there is an explicit "Healing Surges" variant on page 266 of the DMG that makes HD work a lot more like healing surges did in 4e.
