Blizzard did a good job with new balance changes to bonespear necro and Aov crusader which were clearly overperforming in comparison to other classes.
However, they forgot to nerf FB wizards as well. FB wizard also too powerful and needs to be nerfed.
FB players had their fun for a season and now, they should get balanced to the level of other classes for next season. As it stands currently, FB is far more powerful than other classes and can deal orders of magnitude more other inferior builds can dream of doing. Therefore, they need to be nerfed to equilibrium and be balanced with other classes.
This is the only way other inferior classes can have some fun too. Let dps barb , dps dh, dps monk, and dps wd have some fun in competitive group play. The problem is that noone wants these inferior classes outside of Zdps support builds because FB wizard and other over performing builds is far superior and deals much more damage.
Also, off topic but Rat necros builds need to be destroyed entirely. Even though its not as a strong as the wizard speed meta, it is also far too powerful and for far too many seasons.
