Race Points and Tieflings

[Doki-Chan]

Tieflings with no messing cost 13RP.

I was wanting to create a variant that was based on Erinyes, and so wanted to get (at least) the Vestigial Wings (possibly better flight), and possibly a Weapon Familiarity (All Bows and Whip - to use a rope like a whip like Erinyes do), and replace the spell-like with Animate Rope.
My GM said if I wanted decent Flight, as Vestigial Wings were 2RP, to balance I'd have to lose some part of Fiendish Resistances. Fair enough.

It was at this point, however, when paying more attention to the individual costs of the Racials and Alternate Racials .
Ignore Weapons for a moment...

Vestigial Wings (2RP) Replaces Skilled (4RP). So now my Alternate Racial Tiefling costs 2RP Less than a Regular Tiefling.

Is it acceptable to ask for something like the 30'(Clumsy) 4RP cost Flight instead and that then it should balance? I wouldn't mind losing just one resistance then to pick up the Wpn Fams. (or at a push Glide to stay evens on old/new cost)

(I will just add I was going to get Infernal Bloodline but was maybe picking up Seeker instead so would lose Wings option at 15th Level and I'm not spending 4 feats on an Eldritch Heritage to get proper ones either.

I also know there are spells/feats to either grow (or strengthen existing) wings and would not mind starting with 4RP flight and then doing an upgrade with a modified "Flight" feat (see strix, for example)

However, the point remains that swapping Vest.Wings for Skilled Does Not Add Up.

No-one?

I might have rambled a bit in the last post: so here goes:

Tieflings cost 13RP.

If a tiefling wants "Vestigial Wings", (2RP) it costs them Skilled (4RP)

Can someone move this to Errata if that's where it needs to go?

Many of the Alternate Racial traits aren't a 1 for 1 swap. They're not meant to be. They are options to enhance a concept, rather than packages of identical degrees of power.

You could probably enhance a concept without having to give up power in exchange (unless you want to). Or without getting bumped up in power I guess, since that also exists.

Of course, all that assumes that Race Points are not a cluster of fudge and the options of similar values are balanced against each other. You are probably better off evaluating the trades on their own merits instead of point costs.
