BTW, playing a warrior in D2:ED with a bit of bow use early in the game, I left my creature as a warrior just by default. Later, entering the fjords early to level before going to Sentinel Island, I had a lot of trouble trying to take out some level 21 imps at level 17, and found that my creature was much more helpful with a level 2 ranger head than a level 6 warrior head, and I later switched to a mage head. As a ranger/mage the creature seems more aggressive (sometimes as a warrior he could take awhile to join in a fight, and didn't use Rush Attack as much he could have), and doesn't move around as much (so can be useful as a shield).
