I play French national deck as Nato, so I use F2s and HOTs. F2s don't come on any vehicle, making them pretty redundant in the current meta. No good player relies heavily on foot AT teams. You want wheels under your ATGMs. I'm coming to a point where I'm considering removing the F2s from my deck, they're just not useful in the current meta. Too vulnerable to artillery, especially due to them having only 2 health. Konkurs foot teams it's pretty much the same thing, except it takes much longer for artillery to root them out of buildings. This is a huge advantage in the artillery centric meta right now if you do insist on using foot AT. But neither units are particularly amazing atm.
HOTs have power but the 1 less accuracy is pretty huge, I find them unreliable unless you go with really high vet. At which point the availability becomes painful. Using both HOT and Konkurs extensively atm, Konkurs have a noticeably higher hit ratio.
I don't know what player actually consistenty loses heavy tanks to ATGMs from NATO, but if that's a problem for you then you need to rethink your playstyle. ATGM cars don't have remotely the utility against Pact tanks as they do the other way around, they simply get countersniped even if they manage to hit their first shot.
Post some replays though, I'd love to see you play high ranked players and proving me wrong. What team do you play with? For some replays of my play just check the replay repository for those tagged with EPIC. If you want more I can throw some at you.http://alb-replays.info/#/browse/?searc ... ked=0&ai=0
