What.
I love the Flak HT, it's my most favourite unit when playing OKW.
It's like a suppressing and more defensive Luchs. You just have to mikro it a bit and keep in mind of the aiming time bug, but otherwise I love that thing.
Actually, after you play USF, you will understand why Flak HT is not that good.
Before OKW was redesigned, Flak HT fuel timing is 40(tier2)+40(cost)-40(start)=40/0.67=60 fuel
When OKW was being redesigned, the first truck can come out immediately, thus OKW flak track cost is increased to 55 fuel.
Now, after push back OKW tier2 because of luch, tier1 was also affected, and the Flak HT fuel timing is 40(tier2)+55(cost)-10(start)= 85 fuel
I notice this when I was still convinced that FlakHT is okay. But after getting outtech by USF, I recheck again and realize why.
Btw, USF HT is 50 fuel only and way superior to OKW.
