The mortar is not bugged, it's exactly the way relic intended it. Guess what, Mortar was fixed today. You know what happened? It got even better. It's range was lowered but it's accuracy and rof is now even higher.
Yeah, it's a tier 0 At unit with a cloaking ability that is also very bad.
Because it costs 55 fuel to get healing. That's fifty-five fuel.
Here, let me give you a list.
USF: 250mp and 10 fuel for healing.
UKF: 30 munitions for healing.
SOV: 250 manpower for healing
OST: 200 manpower and 60 munitions for healing
OKW: 400 manpower and 55 fuel for healing
Find the outsider
You seem to know more about it then the closed beta testers, that report that it wasn't acting like this in the beta.
USF = Not a rally point, not a tech building that can call units.
UKF= The worst healing ability in game, price is all it has going for it.
Sov= Limited to HQ building, talking of a nation severly limited in many other fields comapred to OKW.
Ost= fragile medi bunker.
OKW= Rally point ability, tech building, and units plus a very good healing ability.
You are comparing apples to oranges. The only way the OKW old healing station is anywhere near justifiable is if they have the economical handicap of old.
