Hearthpwn

I'm a bit confused by OP. The devs exactly pointed out that Kaz got nerfed to avoid polarizing druid even further. Nobody accused Kaz for being the "meta breaker", even thou the devs called Kaz a solo win con. So, Instead of killing the tempo or survivability of ramp druid they went for the late game win con, to give control decks a better chance against ramp. Other decks like dragon priest and control warrior should (hopefully) be able to play 4 dragons before, so you could call this nerf an attempt to move Kaz from only the typical ramp druid deck. Now if that will ultimately work I can't tell and it's too early to know anyway. I don't think that anybody disagrees that the main strength of ramp druid is... ramp. It's guff that carries the deck along with the mana gain/refill/cheat. Aggro still punishes ramp by nature, so maybe a 1 turn delay of guff won't make the game any more enjoyable, even thou Guff is an over tuned card.

Btw: That people argue with your "anti fatigue is the main purpose" argument is pretty expectable since you presented it as your main point, even if that wasn't really your standpoint.
