A few people have mentioned they've implemented a house rule after character creation of adding up the DP of the characters to make sure they are ~125, since some of the skill combination rules can "bleed" points and make some characters more powerful than others.
My question is how to add up these DP? Most things can be added easily using the DP table in the rulebook, but when it comes to skills things get difficult.
Say for instance I have a skill level of 2(4). Since it costs 3 DP to get a skill at 1(2), what does this 2(4) skill equate to in DP? If we go by the same DP values no matter what the level, you can say that to get a skill to from 1 to 2 costs an additional 3 DP (but does that make it 2(2), or 2(3)?? It isn't clear).
After that, the specialization then costs another 1 DP. So, depending on how you look at it, the DP is either
7 (3 for 1(2) + 3 for 2(3) + 1 to make it 2(4))
OR
8 (3 for 1(2) + 3 for 2(2) + 2 for 2(4))
Things get even more complicated when you have multiple specializations. The gap between the DP costs get further apart with various specializations... a skill at 2(4)(4):
9 (3 for 1(2) + 1 for 1(2)(2) + 3 for 2(3)(3) + 2 for 2(4)(4))
OR
11 (3 for 1(2) + 1 for 1(2)(2) + 3 for 2(2)(2) + 4 for 2(4)(4))
I personally prefer the first style, that when you spend 3 to raise an overall skill, that includes training in your specializations so that you add a point across *all* of them. But with a skill with 2 or more specializations, it becomes more cost effective to simply spend 3 pts to increase the skill as a whole, instead of trying to raise specializations. Which is probably why in the Rewards section it is more than 3 XP to increase a skill (and the scale goes higher as the skill point increases). It is also mentioned somewhere (I think in the Rewards section) that if you raise a skill to the same level as the specialization, the specialization simply goes away (as you are now just as skilled in all aspects of the overall skill). So that doesn't really help to solve the problem.
Any help to clear the confusion would be appreciated, especially for those who have implemented house rules requiring adding up DP totals after character creation. What do you use for skills that are higher than 1(2)?
