What's now clear to me is that EA being limited to a small portion of the beginning of the game might not be the best way to gather feedback. It shows that players didn't have enough farsight in order to leave suggestions about certain matters.

Like, Wyll didn't have to be an outright badass hero with no flaw, he could get his peak development in the later acts. But we didn't have the faintest idea of what's to come, so our judgement shrinked to the miserable Wyll we got to play around with.

We didn't have a chance to playtest the high level combat either, yet somehow we had to give meaningful suggestions on how to improve and balance it. Therefore we ended with pathetic spells like Grasping Vine and overpowered consumables such as Arrow of Many targets on release. Hm.
