Is the fact that characters can come back from the dead a good or bad thing for the game of D&D? From a player perspective nothing sucks more than spending countless hours building up and developing a character only to have him get killed permanently. The creators of the game understand that the fun ends when the PC dies so they introduced mechanics to bring dead characters back to life.
Sometimes these mechanics are as simple as the DM waving his magic wands and the character is suddenly back in the game (which is pretty much how it works in most public-play scenarios like D&D Encounters and LFR). Sometimes the mechanic is a little bit more difficult, but not out of reach. In these cases the PCs spend the appropriate resources to have the dead character returned to life, and depending on the power-level of the campaign the PCs may even have the power to do this without any outside assistance. And then there’s the situation when an entire campaign arc revolves around getting a fallen hero resurrected. It might be a quest to get the necessary material components for a ritual or the search for an item or artifact capable of such powerful magic. The point is that death is rarely final in D&D.
