D2R doesn’t have that many builds that are both inexpensive and viable, but with the more expensive gear the variety of builds increases tremendously. It’s however a rather big hassle to experiment with these builds or try out unorthodox builds both because of the expensive and rare gear and because one might feel disinclined to waste precious stat resets for experimentation.
It would be really cool if there was a creative mode in offline single player on consoles where trophies are disabled and where you can freely edit the stats and the gear of a temporary character.
This would not interfere with the gameplay experience of others because it’s offline and not trivialize the trophies because they would be disabled. It would however make experimentation a breeze, allowing people to study easily even crazy ideas, and would be useful for, e.g., console players who would like to create content such as build showcases.
