You make some good points, but some of the issues you are describing are very D&D. There’s no perk tree and the character sheet is quite general because you can literally switch classes every level if you have the stats for it (not in the game yet, but once they introduce multi-classing). I agree that there could be more informative sections in this game to guide you through character building and management, but there’s no real way to map out a tree like in other RPGs. I mean, you could but it would be extremely convoluted and immense for no real benefit. The way D&D Beyond do it by showing your options for each class level in the form of a list is probably about as good as it’ll get.
