Ok, so I've run the numbers over the current system, and (assuming a -ASI is only -1, not -2 pt) I have the following numbers:
[SBLOCK="Race Points"]Aasimar: 12.5 (Assuming each transformation is a 2nd level spell, and stating their heal as a damaging power taken from the average damage at average level (10.5 at 11))
Firbolg: 9.25 (2 noncombat spells as same level, then hidden step as a noncombat spell (invis) two levels early)
Kenku: 12 - The most balanced race in the book
Lizardfolk: 20 (Hungry jaws as damaging power for average damage and counting thp as damage, assuming a con mod of +3)
Tabaxi: 15.25 (That speed boost is 60 feet half the time, assuming no ability bumping speed, but if you have an ability to dash as bonus action that is a speed of 60 + 60 + 60 in one turn then 0 the next (average 90), which once your speed increases, shoots ahead of not having this ability)
Triton: 20 (3 combat spells at same level wizard gets is 12 alone)
Bugbear: 9.75 (assuming no weight on PB, treating it as reach 10 1/2 of the time)
Goblin: 13.75 (Fury of the Small - Damaging power, same calculation as Aasimar heal but 1/short. range is wonky (literally any range), so gave them benefit of the doubt and said range 5 feet).
Hobgoblin: 18.5 (Save face as a combat spell equal level, 1/short or long rest)
Kobold: 4 (Grovel, Cower & Beg same as Save face)
Orc: 8 (again, negative ASI taken as -1 point, not -2 points, same as kobold)
Yuan-ti Pureblood: 28.5 (still)[/SBLOCK]
This is an average of 14.3 points under Coronoides' system. Bugbear, Firbolg, and Orc are all under by 2.25, 2.75, and 4 respectively, so I'd estimate that Powerful build is 2.5, and estimate that a negative ability score is worth nothing, which would bring Bugbear up to 12.25, Firbolg up to 11.75, Orc up to 11.5, and Kobold up to 5. Grovel, Cower & Beg may be worth more than I gave it credit for.
Yeah, I think re-evaluation of the Goliath might correct those other Powerful Build races, and Aggresive might need a rethink, too.
Grovel, Cower and Beg is pretty huge, actually, as is Pack Tactics.
We have doubled the number of base race examples, so the model has more evidence to work from..
Magic Resistance is probably overrated, though it is the best ability the YuanTi have.
