The fuck does that have to do with not having a tier 0 hmg? You don't use hmgs to counter hmgs
OKW can have trouble with hmgs because of their access to indirect (which has been partially fixed)
USF doesn't have a tier 0 hmg either, do they get spanked by mgs? No. Because they have a mortar
I don't think you understood what I said.
I meant that if you play against OKW, it is a viable tactic for you to use hmg on them because for the first 5-10mins of the game (barring some masterful micro of kubel that only <1% of players possess) they cannot under any circumstances respond to that. No mortar, no smoke. Maybe flanking I guess, but a good player will make 2 hmgs to defend mid and flank.
Anyway, my point is that OKW have no hard counters to hmg play and that fact if used properly can pretty much annihilate them from the get go by a decent allied player for example by starving them of fuel or muni and bleeding their mp.
