So far I belive I heard three criticisms:
1) The tier system is inaccurate.
2) The points don't work b/c Tier 2 & 3 characters get too many feats.
3) Feats suck so bad that denying feats to casters and giving extra feats to non-casters won't balance things.
On 1, let's ignore that for now, the classes can be re-bucketed later.
On 2, I will work on it - see below.
On 3, if that is so, this system won't work. I admit it readily. I would just be curious to see.
OK (altered items in red):
1) Level advancement works as normal EXCEPT you don't get any automatic feats (i.e. 1st, 3rd, 6th, etc.).
2) Each level you get 20 build points. You can save build points and carry them over to the next level.
3) Levels:
___a) Taking a level in a full caster / Tier 1 class or a PrC that advances casting costs 20 build points.
___b) Taking a level in a Tier 2 class costs 17 points (based on JaronK's tiers for now).
___c) Taking a level in a Tier 3 class costs 12 points.
___d) Taking a level in a lower tier class costs 5 points.
___e) To be clear, this is NOT gestalt and you can only take a level for which you have the appropriate XP.
4) Feats are 5 points each.
5) LA buyoff is 10 points per LA.
6) Build points may also be spent on:
___a) Skills: one point per skill point, no more than 5 spent per level this way, same max ranks as normal.
___b) Ability boosts: 8 per point of increase (not sure if 8 is right - TBD).
