Are certain Blitz Units restricted to ONLY Blitz?

Take the Ironclad Hunters for example, the Lifesteal Grunts, or the Armored Warthogs. Are these units available only in Blitz mode? Or will they carry over to other modes like Deathmatch?

I think some of them will but idk about all of them

I think many will be Blitz only. The wheel interface is not complex enough to introduce many of these upgrades into the default gametype.
