I would suggest to you to think twice when pointing out what someone else misunderstands, because you've spent so much time trying to correct something that you didn't need to correct. I don't at all suggest for Dancer to off-tank anywhere near as well as an actual tank, or heal anywhere near as well as an actual healer (if they were to heal at all). From the very beginning I limited the idea to tanking one enemy at a time, and I further expanded that even this should be limited.
I'm sorry, but your observation that I've proposed for a DPS to have a tank stance or similar is unwarranted and not based on facts.
What you've decided that I've implied is not based on facts.
You've simply taken terms that have regularly been used as general blanket terms and arbitrarily decided fit specific things, and then disagreed with me for having used those terms that you decided that I had used incorrectly, when even if you could obtain a general consensus as to such, still does not go to the heart of the discussion.
