D2 sure is old. Interface is clunky: switching to a skill through a hotkey and then casting it with a mouse is so 2000, no hotkeys to move items between stash and inventory (moving 1 tile items around got annoying fast and I didn't even get to Fauztinville), no autosorting (the first ARPG with sorting was Sacred and this is the old game too, so D2 is THAT old), potion system is a busy work, no duration for buff/debuffs shown, LCS, various containers require kicking one-by-one instead of dropping an AoE on them, shared cooldown (without showing the counter ofc), no item filter.
The gameplay is still stellar. I don't know why modern devs can't understand simple truth that I don't want to run around with a shitty fireball for half of the game, even Grim Dawn is affected by this plague (TL2 was kinda using the same system as Median, but alas it missed the point of having low lvl reqs for most skills).
I was a bit surprised at crafting orb changes, but I got through Hatred without bothering with them so I guess it's alright and I am not assed to get through cubing this early in the game tbh.
Somewhat funny is I had to take on LC1 wearing TU Great Helm and some rare Tower Shield, which gave my melee sorc a tanky legionnaire look. Slow running speed didn't help to shake this feeling off either.
The interface is a real deal breaker for me though. I guess I will level my sorc to 90 just to see Baneblade in action, but honestly GD is more pleasant to play, even if its combat system is interior to MXL and downright annoying at times due to random enemy equipment.
