I guess racial ultimates made race balance much harder to achieve.
Now that these skill lines are out there, something that I feel should be made clear to those who worry about race balance or who have the idea that your build constrains your race choice:
The one "free" racial ability you have (no skill point needed) is in every case a 15% increase to experience gain rate in a skill line. Since skills have soft experience caps (I THINK it works by diminishing returns), this bonus only gives you a temporary advantage; you can level that skill line faster, but everybody else will catch up with you after you hit the cap. Which means that at max level, the free racial passive doesn't make any difference at all.
The other racial passives make more of a difference, but they have to compete for your skill points with every other passive in the game, and for each of them I believe there are other ways to achieve equivalent effects (health/magicka/stamina availability, resistances etc) -- either via other passives or gear. Obviously I don't have all the numbers available to crunch to prove this, but from those where I do have the information to assess, it seems to hold.
Which means that really, particular races may advantage particular builds while leveling, but ultimately any build works with any race.
