MY problem overall is that 4e was a revelation, and brought the core game closer to what I have always wanted... It was FAR from perfect, but what it needed was another year or two and a 5e that built from it up not throwing it out for a retro game.
4e walked so... nothing 4e stumbled alot and all the (well most of the) lessons learned got gutted for 5e.
5e is an okay game... but one that just doesn't fit what I want from D&D. 2e is great as long as you keep your rose colored nostalgia glasses on. I would not go back to a 3e/3.5/PF game if you payed me, and 1e/basic fall between 3e and 2e for me (since my nostalgia is for the 90s)
4e was my game... it is my game, it's just hard to code into virtual tables.
my 2 groups are currently playing Rifts, Torg, 5e and 5e. both 5e games has players that want to play TSR versions more, 1 5e game has players that want PF/3e, and both have players (me only in 1 case, half the game in the other) that want to play 4e. 5e is our compromise and we are holding out hope the new PHB will somehow make all of us happier.
