You never played D2, did you?
Frozen orb times infinity is hardly tactically demanding.
Exactly, which is why I called it mindless. Pay attention.

I like hack and slash, personally. Frankly, the design of the game so far looks fucking amazing. I think they've gotten really creative with the monsters and spells and levels and such. I could agree that the color pallette is a titch bright, but it still looks like it's going to be great. It'll certainly blow the likes of D&D heroes and BG: Dark Allaince out of the water, which are the last hack&slash games I played.
Oh absolutely, hack and slash is great fun. Mindless hack and slash not so much, at least not for me. And I don't really see the creativity you speak of. The Shaman seems to be a Necro knock-off, and a wall of zombies? That's just pathetic. It's the result of a thought process like this: "Okay, we want to give the
Necro Shaman the wall-that-damages-enemies capability, but wall of fire is already taken, so let's brainstorm for something in keeping with the character's theme before we go for lunch." It's the opposite of creativity.
The only really new things that I saw so far are environment destructibility (which will become immensely boring after a while) and the shields actually used to block blows. That might be a
very interesting gameplay mechanic if the players are also given this capability. Paladin blocking a door while the sorceress blasts the hordes inside, anyone?
