Welcome to the forum
I won’t respond to points that I agree.
3- Although resistances are important, they are very easy to max overall (augments, components, gear, devotions) … wayyy easier to max than in Titan Quest (the first one)
4- Resist reduction doesn’t limit builds much, there are hundreds of builds in Grim Dawn (literally hundreds !) and more to come with the next expansion
6- I personnaly prefer finding gear into the world over having an arpg focused on crafting. Grim Dawn focuse more on MI (Monster infrequents) for exemples which enhance the world by making you go on different locations depending on the build you wanna make. Last Epoch and POE focus more on a randomized end game which goes a litle bit better for the crafting they are going for.
Is there something else that could be done over what exist in Grim Dawn for crafting ? Maybe !
One thing for sure, we will be able to reroll affixes (prefix and suffixe) and the seed quality (seed quality = how high the stats rolled) in the upcomming expansion Fangs of Asterkarn. You can read it in this misadventure.
Also on the point that Grim Dawn focus more on the world, Fang of Asterkan will make the campaing more the end game with the Ascendant Game mode, you can read more about it on the this misadvanture if you didn’t see it.
