Argh... I went off on a tangent about feat emulation as a possibility for a new mechanic for 5e, when what I originally intended to do was state an experience that I thought was related to the point the OP was trying to make.
Power vs. Options.
Initially we were using the Black Company action points for the raw numerical power they gave us as a bonus to d20 rolls, but once we picked up on the value of emulating feats, and thus increasing our options, the feat emulation became the preferred mechanic over the numerical increase. Having the potential to do more things improved the game for us, as we were more likely to try new things we hadn't done before.
Although for my group of players we obviously drifted towards options over power, this might not be the case for other groups. Some people prefer to play a powerful character and are not particularly interested in doing new things, but rather, doing the same things better and better. 5e might be better off allowing for either type of progression with add-on modules.
