Combat is a pretty critical aspect of the game, and speed, is by far the ONLY attribute that you have to increase. Screw having any others, more action points = better everything.
Basically, this is an issue that I see that needs to be resolved. This ability/attribute is SO vital to combat, that it just... it screws with actually building a decent roleplaying character, simply because combat is almost impossible if you only have 5 ap (that's like... 1 attack?). So in order to actually have a chance in combat, I have to completely sacrifice all other abilities. This includes strength, dexterity, intelligence, whatever... And then focus my talents in whatever gets me bonus AP.
There is just something fundamentally wrong with this.
If I were to make a suggestion, I would separate moving and action points and have them separate. So, moving would would consume a different bar, and possibly be influenced by different attributes, and action points being what you would use for actual combat or interaction.
This is just a thought, but it's a major concern of mine, being one of the bigger backers of the project.
