I just assebled 6x Ripperdactyl for my Shadowstrike. If terradons will suddenly become better than ripperdactyls, stegadons better than bastiladons, trogglodons better than carnosaurs and saurus warriors better than skinks, it will be a bit disappointing for me, because I was going to return to 40k for a while.

Not that I wasn't going to have all the range.
Jokes aside, I hope they won't be nerfing working stuff. No matter, how powerful some of our units are, none of them broken. Even feared Thunderquake Bastiladon has enough weaknesses. Tuning up stuff like Saurus Guard or Trogglodon and creating additional synergies through allegience abilities, magic and battalions - that is what I expect. I don't want summoning to change either, because it is balanced right now too. Also looking forward for builds without Slann.
Beasts got only spells and terrain models.
