Hero Roster Capacity

Anyone know the formula/schedule for the Hero Roster Capacity?

Before the update I was level 39 and my roster capacity was 105.
After the 1.2 update my roster capacity was decreased to 99.

I just achieved level 40 and my roster limit is still 99.

When the patch notes use vague language like “we evened it” you can bet it was nerfed.

With this patch, buying hero capacity with gems will now be a more natural organic experience.
