"Everything good ending on Cartoon Network is TTG/Johnny Test's fault" has the same effect as "Everything good ending on Nickelodeon is Fanboy and Chum Chum/Sanjay and Craig/Breadwinners/Pig Goat Banana Cricket's fault".
How about you guys start giving chances to watch other shows on the network? TTG is not the only show around.
There's Craig of the Creek (that has similar artstyle to SU), We Bare Bears, Victor & Valentino, Summer Camp Island.
And it's not the end of the world. Plus, these shows I recommend had some SU/K.O elements to it. Both Craig and Bears had some SU people involved with it. Estelle sang the theme song on the WBB opening and Craig has a similar artstyle as Steven.
