I play melee types in act 1 - even if they will switch to casters in act 2.
I always take the same approach - run to the nearest and whack it, when it dies run to the second and whack it etc.
I find the fight an easy one because BD allows unlimited use of healing potions with no loss of a combat turn, and the Battlefields provide easy access to large quantities of potions. So the fight can be summarized as a whack and suck fest <don't say it - don't even THINK it>. The pause command is your friend.
