Having read your review and played through the entire game as a Fighter on the Xbox 360 version, they obviously did a terrible job porting this game to PC, as far as the UI & controls go. I actually had no problem running into hordes of monsters and coming out alive using nothing but potions, as well as being able to making auto-target melee the target I intended it to.
While minions aren't one hit dead I do feel they did a good job of making them feel like minions in context to their game, as it is pretty rare to miss an attack as long as the monster is in range and with how quickly you can attack. So if they were absolutely true to D&D 4e in regards to them dieing in one hit it would make them completely worthless, especially later in the game.
Also, only fairly early magic items are 'damaged' to maintain balance while still giving you a choice on what you find most important at the time. Like a short sword that gives -1 dmg but +1 fire damage which will help out versus monsters weak against fire damage or still allow you to do some semblance of damage versus monsters that are strong vs slashing damage.
