When you increase the number of skills by 4 but only increase DPs by 2, of course there are going to be problems.
um, if you currently have 25 skills, and say 50 DP, and you up that to 100 skills and 87.5 DP using your 1:2 ratio, you are doing roughly what I was doing. . . .the actual ratio matters less than the fact that there's now a lot more DP in play.
Because the "Flat" addition of DP as you add skills actually does lead directly to the sort of deflationary problems being discussed. . .for an example:
if you take RMX, add 10 skills, and 5 DP/LV, you can ignore the new skills and spend those 5 DP per level on original skills from before the addition, it will cause skew.
i.e. a tank fighter, built just using the RMX system + 10 skills from EA and +5/DP level will end up being considerably more powerful than a straight RMX fighter. . .and by "more powerful" I mean measurably and objectively more powerful.
If I'm not mistaken, you'd be gaining the equivalency of an extra level every 7 levels that way. shrug. It's a good off the cuff fix, but It is power inflationary, incredibly so as you increase the size of the skill list.
As to the "Per level" limits on skills. . . .with core RMX you cant "Double rank" all your core professional skills, if you add in more DP, you can double rank one more skill, that's a signifigant gain. . .but that's the paltry gain for arms.
Spell users. . .I know what I'd spend an extra 5DP per level on as a pure caster. . . .
(As long as SLA exists, more DP/LV is power inflationary on that factor alone, unless something like rising SLA per rank costs balances it out. . .and how do you raise an SLA cost of 1DP/rank or 2DP/rank by 5%? 10%? . ..with actual costs that low, a rise of 5DP/Lv means 5 or 2.5 more ranks of SLA per level.)
I think you do have a fix for that, if I can read out an answer out of the back and forth between you and Ill.
So say "Climbing" doesn't get split, remaining "Climbing" as the skill set unfolds fourfold and the amount of DP has now gone up 75%. . . .would that mean that the costs of climbing would have to go up 75% to maintain balance?
