I guess it shows what a shitty community WoW PVP is when so many of them think that this is a legitimate characterization of Blizzard. Honestly I don't even know why you'd want to keep playing if you really thought Blizzard constantly fucked everything up like this.
In reality they are an incredible developer that doesn't head precisely in the direction you desire with their decisions every single time.
Maybe I can help you rephrase that to better get your point across:
BG's will be exactly the way they are now, but with the added bonus that every third week each bracket is rated and grants CP.
P.S. Blizzard likes to encourage the habit of trying out different things and in particular socializing more. Guild leveling and bonuses for queuing in
random dungeons rather than specific ones are examples of this. Maybe they believe that people getting out of their comfort zone and trying the other brackets, as well as making new teammates, is itself deserving of reward, in this case CP.
People can't get over the logical fallacy that because they can't get something new that they want without doing something they don't want to do, then that thing has been
taken from them, even though they never had it before.
