More "realistic" advancement in D&D?

[Garthanos]

Back on topic .... one of the sense of advancement illusions is that players see the numbers (especially when you are still relatively new to the game 3 sounds way higher than 1 .... but ummm it reallly isnt) and do not realize the power curve is so much flatter than in some other games including earlier versions.... like I said to get the raw power bump like I experienced in AD&D at the "beginning" level I have to go up 4 levels instead of 1. For me this is actually something that is fixed from previous editions. The more levels also up the illusion.
