Hi thanks for the reply.

I understand how it works according to the PHB and I do give my players the option of rolling or taking the average HP at the table.

My observation now is that the screen to the right when you click to level up says:

Through experience, you acquire new power.

You gain the following traits:

"Maximum Hit Points Per Level "

Does that mean from here on out I get Max or what?

And I agree not explained very well

We should have the option of choosing to receive either MAX or click a dice to roll our own, or just take the average.
