@archsimkat Say they nerfed them to where they took 8.5 minutes to pay for themselves instead of 6.5 or whatever it is.
That would mean in real terms it would take something like 14 minutes before you start making money on them, but you did get a bunch of decent combatants with good BP for the time being.
I think there's room to nerf them without making them a unit unfit for any particular purpose.
That said,... I don't build them myself as they are now =\
