I think the flack HT is in a pretty good now (perhaps not "in a pretty good spot) right now. I frankly find it better than the luchs as it suppresses from long range and doesnt have to get as close (and run into a mine or at) to do dmg.
It is less vulnerable to AT penal than the luchs. It can see them coming, take a volley of ptrs and suppress the penal and fall back a bit. Then a volk can go forward and force the retreat with a flame nade, then the track can come back.
The only problem is that going it pretty much necessitates at least 2 raks to fend off an AEC/t70 and not getting a puma. Pumas a pretty god-tier so going flack instead of it is a big downside of the Flack HT.
