You mentioned rangers, so I'll use them as a quick example/question.
If you gave rangers access to DEX, STR and CON enhancements... I would take pretty much those with a little filler. I've already got 34 dex. I'd sure as heck put a couple points into CON to go up to 18 and a couple into STR to hit 24 instead of 22. All in all, I would be taking 5 points of ranger/elf dex, 2 points of ranger STR and 2 points of ranger CON. Maybe I could squeeze in some ranger WIS to increase my spell points or some ranger CHA to improve UMD.
While giving every class access to all the stat enhancements would provide new "options" would it not also simply force you to take them to compete? Someone (or lots of someones) would do it. The characters would become that much more powerful again and the mobs would inflate again. Now any character that did not take ALL of them would be "gimp".
Besides, isn't the ability to access all the stats supposed to be the "human" thing?
Do you really want racial and class enhancements to every stat?
I agree that some other races could use a few enhancements to help catch up with dwarves. I agree that dwarven toughness is VERY powerful. Aside from Halfling smallness I'm having trouble remembering suggestions within the thread to improve the other races. How about we discuss some of those? It would be great to see some ideas to improve elves (as an example) that don't try to make dwarven clones.
So far I remember:
halfling smallness - a joke I think.
another halfling one - tiny avenger was it?
elven armor mastery - light only
Lots of folks are made about the good bonuse to axes. What if the elven bonus to elven melee was increased? Or split it so you pick one (i.e. rapier) and get a better one cheaper?
Elven rapier attack
+1 for 1 ap
+2 for 2 ap
+3 for 3 ap
+4 for 4 ap -- total progression cost 10, but is limited to one weapon
Elven rapier damage
same as above
elven rapier crit range
+1 for 2 AP - requires weapon focus pierce
+2 for 4 AP - requires improved crit pierce
elven rapier crit confirm
+2 for 1 ap
+4 for 2 ap
+6 for 3 ap
+8 for 4 ap.
elven rapier penetration
25% chance to bypass piercing DR - 1 ap
40% - 2 ap
55% - 3 ap
70% - 4 ap
These are powerful yes, but limited to a SINGLE weapon which is the balance point. You could give options for all the elf weapons: longsword, rapier, shortsword, bow etc. (But not to stupid weapons like shuriken - who the heck want to specialize in shuriken???) This would be in-line with the more graceful, "educated and trained" concept of an elf rather than the brute force "just wack it really hard with any ole axe" dwarven mentality.
With narrow focus, but powerful enhancements like these, you would also rapidly run out of AP. Taking some of every stat enhancement would not be possible if you wanted one of these lines. Heck you might not even have enough AP to fill out all the rapier bonuses. (I mean, I just listed 46 actions points for rapier alone.)
This would give lots of options. It would give big boosts to elves. This would give elven longsword fighters some bigger teeth. It would boost elven dex melee types as well.
Would this type of thing give you the options you seek, or are you just looking for STR and CON enhancements?
Drow could get same as elves.
Halflings daggers, light picks(?), cross bows(?) and some other small weapons.
WF - greatsword, greatclub, greataxe, maul (each is separate), (maybe longsword)
Dwarves get what they already have
Humans - similar lines, but at 50% of the bonuse but apply in classes. I.e. ALL-Marial or ALL-Simple or ALL-Exotic.
