I got it last night. Not sure if it's better than D4 yet. Gear seems much simpler and easier to find upgrades. Already got some legendaries at level 8. Not usable for my class but still.
Crafting seems useful for the one thing I did try.
The skill trees are a bit confusing at first but there are a shit ton of tool tips for folks who want to min-max. But from what I hear min-maxxing is not a thing like it is in D4 or at least not as important. Each skill has it's own skill tree. So, get the basic spell and modify it to do what you want it to do.
Graphics seem ok so far but I've not payed a lot of attention to them versus trying to get used to gameplay which is similar to D4 but for some reason feels a tad more, strange. Still hitting the wrong buttons too much. Accidentally burning through my health potions trying to cast a spell. But it does seem that if you use a potion then the enemies will start dropping some for you to pick up.
One glaring change is that LE has a VERY robust loot filter. You could literally spend an hour setting up just one loot filter if you were so inclined.
One thing that is also different that could be good or bad depending on your POV is when you portal anywhere the place you are is all un-revealed map. So you go back to town and it's all fogged over again. Go back to where you ported from and it too is all fogged over again. The loot chests and mobs all spawn back including mini bosses. So, if you wanted to farm a mini boss then it becomes easy. However, if you were trying to clear the map before moving on then you either start over or just say screw it and continue on.
