Dude, are they paying you to answer to everyone? Why are you so butthurt on this to invest this much of your time LOL
You speak with all this professionalism, but let's check few things:
1) You said you played years of Balance Druid, you claim to play it better than others, but yet you haven't noticed this bug or you did and you joined the rest in "exploit-ing". This is your logic btw, you are a dirty exploiter for using 2 set tier 10.
2) "A decent leader would be taking one only" - Wrong. Inexperienced player detected, opinion rejected.
3) Simple argument he says and then he says "people play it because its viable". Yes, I agree. And now after the change it is less viable. Is that a fact? It is. You want it or not, damage is part of viability. The fact that it's worse at supporting now, due to stealing mana, is also another factor of making it less viable. If you try to counter argument this with your non arguments, you should honestly get banned from being able to respond in this thread to not flood further.
4) You can deny parsing, but your one man army opinion is extremely irrelevant and lost in volume in comparison with the 100k entries provided from Lordaeron & Icecrown.
5) "Prove me wrong. Bring me the evidence that this bug fix will destroy the boomkin population and make everyone quit the game"
This is the dumbest thing I've heard in a while. Obviously not everyone will stop playing Boomie or stop playing at all. But it will cause a damage. Damage at what magnitude will be considered to be a damage? 5%? 10%? 15%? More? The fact that it will cause damage is there, it doesn't require the whole world to stop playing the class.
6) Yeah, I also think that the argument of "it worked this way for 10 years" is good enough. I also think that the satisfaction of current playerbase has bigger value than who will join the server in the future. Satisfying your current customers is what will attract more players tomorrow, not the opposite.
7) No one but people like you would cry if demo or enha were buffed as well. It would change absolutely nothing or it wouldn't break absolutely anything in the game (in the PVE aspect, in PVP it might get trickier with Enha). Demo is known to be useless, just SP bot, thats why its hard to find one. And Enha is just not viable and not taken anywhere (at least on Lordaeron). The only time you see a an Enha Shaman is when when 1 Resto Shaman swaps to DPS but even then, thats usually an Elemental Shaman and not Enha. Gonna ignore this part as well where you say "lets match the dmg of all classes" since its just exaggerated as well like some of the other non sense you are saying.
8) I think people gave a lot more than just "I like it", but that seems to be the only thing that your brain can process. Keep it up.
