Not sure about their performance yet.
But their desing is weird.
Things that should cost fuel (Halftracks, Tank Call-Ins, sidetech for PGs) don't cost fuel.
But then they have the ultra lategame tech behind a 150 fuel special tech.
That is all somewhat confusing.
Halftrucks have wet paper mesh armor unless you invest heavily in upgrades, dingo murderfucks 250.
Battlegroups cost fuel in multiplayer.
Upgrades are all MP heavy as faction is MP heavy and has twice the amount of upgrades as other factions.
I really do not see what got you confused here unless you played DAK just once.
