I think your argument works both ways, you think people who have only played against BW and not played the class to a descent level gives valid input into its balancing argument ? I can say that playing against a class will give you a massively skewed opinion as opposed to playing the class through the game, personally.
Also the healer comment is a tenable one from game perspective, I do lots and lots of damage to the enemy and myself, ergo I need a healer to perform that role, balanced ? I think so
not to say that any other class doesnt need a healer to perform, just that I am literally bound to how well I can perform my role based on the number of heals I receive.
Where did I say we should limit the people who can contribute to discussion? Nowhere. My comment was in response to you saying people who haven't played a BW to high level don't know what they are talking about. Whereas my view is that playing a BW, playing against a BW and playing alongside a BW all give useful information on how the class performs.
On needing your own healer, think for a moment. If the game is designed to support this, what happens to all other classes? You need a ratio of 1::1 Healers to BWs, how the hell do you then balance the class distribution across the realm? You can't design a game that way.
If roughly 1 in 3 classes are healers, with a balanced distribution, the BW class needs to be designed to only require 1/3 of a healer. Of course, there are other complexities that affect it a bit, but that's the basic principle.
Also, how do you explain BWs not being at the top of the deaths in scenarios? You say people only look at damage, but I've pointed this out in clear terms and you have completely ignored it. You claim BWs need more healing, you claim they are the most squishy, but the evidence does not support your claims. That's because you only look at some of the factors.
