Try and respect a few different opinions on the subject. I think the argument is that by taking away the tweaking, tuning, maintainence etc you are creating a class where it is easier for everyone to be equal.
The idea of a spec class is to give everyone the same level of performance so skill is the deciding factor, the current stock rules mean that those with the skill but without the time, money or knowledge are at a disadvantage. Sure it's fun if you know what you are doing but not everyone does.
By mixing brushed and brushless classes you would encourage more people to go brushless simply because they can race with it. This would lead to a situation where eventually you would get a true spec class.
If the current Novak BL is faster than a good stock, then the idea won't work but with the new motor coming soon it would be blinkered of us to not allow people to race with it just because it's a BL, this sport/hobby needs new racers.
