D&D is a tactical wargame on top of a role playing game. Or vice versa. Chainmail that eventually became D&D was an attempt to ask the question "What would it be like if the Wizard and the Fighter from my tactical war game decided to go into a dungeon and kill a dragon?"
I agree 100% that this is what D&D was derived from. However, just because it was derived from a tactical wargame did not mean it did not evolve from being a tactical wargame.
But balance isn't about being a tactical wargame. In fact, in a tactical war game, it's perfectly ok for the Wizard to be the better unit in your army, because they are all pieces that are being played by the same person anyway.
Also, 100% agree. The same can be said with a roleplaying game. If a player wizard is inherently more powerful, the DM needs to make sure the NPC / enemy wizard is just as powerful to balance things out. The same could be said with clerics, fighters and rouges.
Because math doesn't work that way. If wizards are that much more powerful than fighters, than taking out the big bad guy won't matter if your wizard loses. Because the enemy wizard is powerful enough to take the rest of you out once he's done with your wizard. Not being able to take out the big bad guy doesn't matter because your wizard is powerful enough to take him out once he's done with the enemy wizard. The end result is, it doesn't matter what you do. You might as well not have come on the adventure.
I disagree 100% on this. Why is the wizard always more powerful? The fighter could take the wizard out within one round when considering the low hit points. The wizard and fighter are both powerful, just each in their own way. The wizard has a lot of negatives that the fighter does not suffer from - vancian spell limitations, low hit point, crap armor, limited weapons, poor physical saves, etc. I enjoy playing fighters, especially when playing with a good DM. A single good throw of a rock could ruin a mega arch-mage's spell of instant party doom and end a big-boss battle. I think when you get too involved in the math of the game (which is fairly broken, even in 4E), it takes away from the game.
But those aren't the average scenarios people run into. The average scenarios is: Party walks down a corridor, ends up in a room with 20 orcs, roll for initiative. The fighter kills one orc. The wizard kills them all."
Never seen it happen this way, especially at the levels where you are encountering orcs. Fighters and rouges shine at those levels.
