I am thinking of making a Kineticist. They benefit from a high Con (most of their skills depend on it), and a high Dex (for better ranged accuracy). However, the only races I can find that have a bonus to both Con and Dex are Hobgoblin and Merfolk. While they would be viable with some work, I'd like to use a different race while still getting those bonuses.
Would it be unbalanced/game-breaking to take a race and substitute out one of it's ability bonuses?
For example, consider Gnomes (+2 Con, +2 Cha, -2 Str), but swap out +2 Cha for +2 Dex.
Obviously this would need to be with GM consent.
If it is unbalanced, what are some modification that would make it work better?
(I've looked at the Advanced Race Guide rules for races, but they go into detail on a point system which I don't really want to deal with for a “simple” stat bonus swap, and I've heard that they don't work guarantee balance anyway in that you can get some point-balanced races that are objectively superior to others.)
