Based on both my own experience as DM and my own playstyle as player, @overgeeked hasn't had bad gaming experiences; instead he's merely had lots of experiences with the game as it was (and IMO still is) meant to be played.
Like it or not, it's an undeniable fact that D&D is sometimes a competitive game: those times being when the players/PCs are competing against the challenges or puzzles posed by the setting/DM. And there's nothing wrong with this in the least; it's how the game was designed in the first place.
But it does mean, as with all competitive games, it's on the players to try and find an edge and on the referee to keep that edge-finding within the bounds of reason. The difference, of course, is that the DM is both referee and challenge-setter; meaning not only do the players have to be able to trust the DM to set fair chalenges and be a fair referee, the DM needs to be able to trust herself to do what's best for her own game in both the short run and the long.
I think there's a big difference between "Find the tools within the game intended for the purpose" and "abuse tools provided to give the ability to engage with the setting more". The former is playing with a competitive streak; the latter is playing in bad faith.
