Kind of like how Mountain Dwarves balance an armour proficiency that is only useful to non-warriors with an ability bonus that is only of primary importance to warriors?The trick is to have a mixture of things that are useful to some and not really useful to others. Elven weapon proficiencies don't do anything for the warriors, but they offer a boost for the semi-warriors.
This is one of the reasons I am hesitant when it comes to mix-and-match, build your own races. Most races have a mix of benefits to various concepts rather than optimising for one. You can break down the dwarven benefits into points, but any race built on that total by an optimiser will be more powerful than a dwarf, since they will have traded away the abilities that don't benefit them for abilities that do directly benefit them.
