Exactly the same can be said about whole friggin OKW faction and yet its here and not going anywhere with their uber sim city tech, in fact that is being supported even more by all the nerfs to things that pose even remote danger to them, regardless of how huge cost they have(talking about off-maps here).
+1, It takes at guns tanks mortars pretty much every thing you have and off map artillery to normally counter or destroy a well placed flak hq. Thanks to there extremely durable fwd reinforce truck they can also react to defend them very quickly.
I think the brit fwd reinforcement point should have a bit more HP. Mainly I think brit emplacements are fine especially with royal engi it is the giving incendiary grenades to volks that is a problem. I remember most axis players saying they did not even ask for them to be on volks, but on sturms. Too many volks always around with the best AT weapon that also counters emplacements with a cheap grenade that two counter a very expensive brit emplacment. Maybe the bofos should have more HP because it should be able to better be used for area denial like the flak hq. Bofors and cent were over nerfed last patch.
