Awww, yeah, forgot about that, slipped into early 7th ed thinking. Not played 40K for too long.
You can still do silly things with it, fear not - Sternguard with Skyfire is an obvious choice (fuck you, flying Hive Tyrants!), Preferred Enemy Thunderfire Cannon (fucking Hit and Run Thunderfire Cannon for lols), Tank Hunter Stormtalons etc.
It's a really nice bit of kit, but god damn either it or the Rhino Primaris are hugely overpriced (or they're both moderately overpriced, but that's no real consolation).
EDIT: Oh, it's also an Assault Vehicle for six non-Terminator models. Hooray!
