There will be no compensation for autobuild.

Based on the wiki – a toon in their 30s should have roughly 100 hero points to spend on buying into a specialization and skills. At that point, you’re also earning ten hero points every two levels. To earn another 100 hero points from leveling, you will have to make level 55. At 45 you gain the use of a second specialization, so you will end up just keeping the one assigned to you (or one of them, if you were assigned more). It takes 60 points to completely buy out a specialization.
It also seems that by your 30s, there’s about 13 zones you have access to, and with an average of 7 hero challenges per zone (rough estimation based on looking at four or five zones), you’ll earn 91 hero points if you complete all challenges in every zone that’s 40 or below.
It would seem then, that to completely make back what you lost to the auto-assignment, you’d have to do every challenge in every zone you can. To make enough to buy out a specialization, you’d have to complete 9 zones worth of hero challenges. You can also level about 6 times (the actual number depends – more if you’re in your 20s, less if you’re in your 40s and 50s).
Rough numbers, just to keep it simple.
Just to add, my point is that it is doable, but you really do have to hustle for it. The 60 points also doesn’t cover any additional skills you would want to buy.
