If less is a good thing, then how come the people in the group didn't choose to use less? You can make a functional 18th lvl character in 15 minutes, unless you specifically choose to run through all of the different options out there.
The great thing with having lots of options, IMNSHO, is that one can choose to use as much or as little as one wants. If there are much less options, as in a heavily class-based system with limited optimization, then one only has the one choice. I'd rather have a lot more choice and count on my own judgement and ability to choose. YMMV, and apparently does.
