I understand the 1/2e approach. I just don't think it works as well as the new approaches across a large number of styles. While the most common style of those that like 1/2e fits the every changing balance there a lots of styles that don't. Neither are better.
True. I admit that the 4E style works better when the focus is on character power (which seems to be a major element of modern role-playing). I like the 1/2E approach better for organic games as there tends to be more variety of characters and each has an effective niche. Variety doesn't work so well in the modern environment as trade-offs can easily lead to imbalances if one's play style is too focused on one extreme or the other.
So the best bet is to generally balance character and try to make the flavor different. For all of the things that I am ambivalent about 4E for, the ability to do these well (Ranger and Rogue -- both effective martial strikers with a completely different feel) really does count as brilliant design.
