and yes ops owns forge.
last i check fasci forge owns ops. Its very similar to what inflict was saying. if its against a bank post you have to use bank forge gen(2 scouts rest romans). Against eveything else you use a bank forge post(2 tanks 3 scouts X romans). Against bank post you have to apply a constant unwavering pressure that will slowly kill the monarch while against everything else you have to play it like a capi and out resource them. The reason why this works against post is because the pressure you put with romans is too dangerous to be ignored. If you use tanks, you waste your eco because the scouts kill them off. If you call in marines, my romans come in before your tanks can kill them due to the quantity and early field. As for stuff like bank forge, they can be countered because as a fasci, you will always win an air fight and get the pin. However, your opponent threatens a pinbreak by using ops. This forces you to adapt using post 3rd. With that you can squeeze 2 tanks for a pin, while you still have romans knocking at their door. This forces a premature pinbreak. The monarch cannot missile due to the energy spent by the forge. Your prides will not survive due to divisive fire from scouts and tanks. your spec forces would not survive due to divisive fire from your romans and tanks. Im not even going into detail about far snipers. Even if you add in units like scouts, your key units(pride/special forces) would be long gone.
If you try to pin with 2-3 scouts and they turn out o be capi or delayed fasc you are in trouble.
well first of all capi is very easy to spot, assuming they are using meta game (bank post). capitalists bank always clocks at 4 seconds. If they do not use bank post, they would be screwed against a good player. Furthermore, their post and your forge would be built at the same time. There wouldnt even be the chance of spamming those units. if its a delayed capi, you can treat it as a delayed fascist.
As for delayed fascist, this is also not a problem. A fascist who loses field advantage and economy is losing their only advantage. True they can attempt a pinbreak however if you retreat to the second influence zone you will basically be a napoleon and drain them of influence. However lets add a bit of operator error. If you screw up when they pinbreak, you can start a dual build. Due to the addition of marines and tanks, you opponent has no chance to survive. The current situation is that your opponent would have easier micro and a wide macro choice. However you have an influence advantage, field advantage, a resource advantage(energy), and quantity of units, and varity of unit advantage. its like fighting yourself, only that one of you is restrained.
Any decent player can tell you that combatting right side ops with forge is hard to say the least.
The matter of difficulty only comes with experience. In an rts, all that matters is whether you can do it or not. Just hours of proper repitition and reflection will make you a better player and decrease your chances of derping.
