In what way?
It's a grid based game, so you shouldn't try any continuous movement. If that's what you mean by clunky.
What I meant by clunky is that the game, from what I've seen, has you pressing lot's of different buttons to do all the various things and that doesn't look too comfortable.
I see. Well, you'll have to do it for spells. Might be tough at beginning, but I quickly got used to it though.
The only thing I did in MM2 was create keyboard macros for "First Aid x10" to speed things up a little, since First Aid is the most efficient healing, but takes long time to fully heal for high level characters.
If you do find it too difficult, keyboard macros can be your friend.
