So you're crying because your fire isn't green? Wow... That's absolutely amazing.
On topic, you have no business in interfering with Blizzard's decisions. It is their game. You paying the subscription fee is merely for Blizzard to be motivated to bring out new and better content. While I do agree that they somewhat fail on that, I also think you are not obliged to pay the sub fee. Noone is forcing you to pay and/or play.
Seriously, if I could have kept my mouth shut for the 6 years all ret paladins wanted better mechanics and that which EVERY SINGLE CLASS has/had (a slow/snare) then so can you keep it shut for some stylish new green-fire effect. Seriously, back in TBC no-one wanted ret paladins. I was greeted with a "go holy or go home" quite often. And yet I kept my mouth shut. (It was a different story when I out-dps'd the mage but hey!)
So yeah, less Q_Q, more pew-pew!
