"Warrior" is another reasonable option, but it skews almost too far towards the generic. It's a term that could be applied to almost any character that was focused around weapon-based combat, but not sufficiently martially trained that the term "soldier" would feel more applicable. It's not particularly evocative of a character becoming especially enraged or otherwise focused during combat and gaining extraordinary offensive and defensive benefits as a result.
"Warrior" isn't that overly generic than "fighter" or "rogue" however, whereas both terms can be applied to a very wide range of character, independently from their class abilities.
