Right, but I can't say that either of those extremes are being heavily advocated in this thread. Just a lot of GW1 references, which at least have a bit more merit than WoW ones.
Regardless, you're not encouraging anyone to do anything "wrong", just going about it the wrong way. I absolutely encourage anyone playing however they'd like, but I think it's more important that they look into and become aware of the strengths of their class.
And yes, the game isn't perfect and can still be fun, but that doesn't excuse it from being fixed.
