I don't have Liberators, Hades, or any of the newest must have units.
I don't even have the decent Shadow Ops stuff from the last 6+ months. My best units are BFG X, Kara, Cyclones & ETitan, along with Jackals & Nightmares.
What units should I focus on trying to buy over the next few events, what should I ignore, & what should I focus on upgrading to get up to snuff with the current unit power curve?
I am able to take Corpus 70s & 95s Sandstorm bases on my own. I've yet to get it though.
