Derek,
There's an issue with almost every edition and they all play very differently from one another. 4th edition isn't really wrong it is just that it was a polar change from 3.5. The reason being new players found it intimidating to figure out character creation and it's complex rules which gave more options for a realistic fight. 4th edition is much easier to pick up and play since the power cards and feats essentially drive how a character is played and attracts the mmorpg crowd to playing, which right now is a huge audience to tap into. Unfortunately this did not lead to sales or anything great but at least the older players are dissapointed enough that the new edition will seem an improvement and attract everyone, almost like a cash rollercoaster.
Besides, 4th edition does solve balancing issues a lot better than 3.5. The only problem is classes such as the Druid and wizard, two previously very different classes, now play almost exactly the same leaving the impression that there is no reason to pick one class over another. Even the heroes of shadow us surprisingly hyper balanced in regards to mechanics.
All I can say is that a real player/fan of the game will have to roll (pun intended) with the punches and just play the game for fun and leave concerns behind, because every new edition will make a select crowd very happy and another crowd very unhappy.
