# What are the most common design problems found in games based in levels and classes? [closed]

I am starting to develop a home-brew system along some members of our group, and one of the things we have to decide is the advancement system. We are divided between point-based and class/level, having experienced and enjoyed both of them. After reading this question about the differences between those two, I stumbled over this other one, where the most common flags of the point-based system were discussed, and now I want to make the same question about our other candidate.
The first question linked contain some interesting answers, but those are more centered on players and DM interaction with the system, and I would like answers more focused on the issues on a game design level, like those in the second question.

Concretely, I would like to know the most common pitfalls in those systems that would encourage players playing the system instead of the game, aka powergaming.

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

This sounds like a too-broad list/opinion/discussion question. Can you narrow it down a bit? – edgerunner Nov 7 '13 at 22:50
This might be the other question's compliment, but unlike the other, this one is not very specific and is very broad. The point question is asking how players might exploit the system: this is asking about the flaws in general of the entire game. This could be asked better. – doppelgreener Nov 7 '13 at 23:36
Edited question to narrow it down. – MACN Nov 8 '13 at 9:36
Tempted to reopen but it could be more specific. "What are the problems" is kinda vague and just seeking opinions. Even the point-buy one you link specifically asks about player exploitability. Consider how to ask what you're really concerned about. – mxyzplk Nov 11 '13 at 13:44
