This shift will only effect random stuns. Abilities such as Warstomp, Seal of Justice, and Kidney Shot are not on the hit list because they are cast as stuns, not at the mercy of the RNG. In addition to concerns about the shift in ability itself some players are disappointed with this change because it leads to further homogenization among classes.
According to Ghostcrawler these changes will take some time to implement. They will require a shift in talents and, in some cases, compensation. Sorry, my feathered brethren as it stands there appears to be no compensation for the Starfall nerf. Don't be surprised when your random-proc stun vanishes.
