I think people's responses will vary based on the class they play most often and what classes counter them. As a 1H shielder, I hate people who use a polearm, face away from me, do a complete 180 and stab me in the face within a fraction of a second. They're second, however, to maulers who I'm unable to get close to without being knocked down and raped. Cav are annoying but can be countered if you're clever about using the environment to your advantage, or if you can feign ignorance of their presence and use their false sense of security to turn the tables on them.
