Additionally, you have to consider leveling, what ability would you be able to use while leveling a feral druid? You won't be able to get behind mobs unless in a dungeon so you'd be left to spam Rake pretty much, a minor point for us end-game ferals, but would definitely affect the leveling aspect.
Defensive cooldowns seems like another area to get nerfed, Might of Ursoc, Survival Instincts, and Barkskin seem excessive.
Aside from that I think it's just best to wait and see. We can always speculate, but only 20% of our abilities are being cut or merged, so I think it's a lot less than people think
