Dont worry, dude. T70 has been due for a nerf for a long time. Has very little to do with Industry.
And don't worry, your use of the word "luck" didnt confuse me.
The word just doesn't mean what you think it does, nor does it apply to Mines.
Talking to you it's like talking to a wall...
T70 got nerfed few times already and now it will get nerfed even more cos that's how it is in CoH2. As I said before I expect every decent unit to be nerfed in the end. The system is simple. Is unit capable of killing other German unit by it's own? If the answer is yes then the unit is clearly OP and it gotta be nerfed.
How luck doesn't apply to mines? It does. If you're lucky enemy tank will be blown up by a mine. If you're not then it won't. If you're semi lucky mine will kill some less value target. If you're not lucky at all it will be blown up by an accidental shell and you'll waste 30 muni. Simple?
But the best thing is "I watch a lot of replays so I know Soviets". I will tell you something. I watch a lot of music videos and people singing but that doesn't make me a good singer. I watch a lot of people flying planes (a hobby of mine) but I have no idea how to fly one in real life. I watch a lot of F1. You got 1st person view camera and you can see how they drive but I don't have a clue how to drive F1 car..Damn I watched a man walking on a moon once does that make me an astronaut?
To give you game example. I play Dot2 and watch pro scene a lot. There are some heroes I'm familiar with and they are some I'm not. I watch them all and I know them all and I know what they can do but I have no idea how to play them or any deeper understanding of their mechanics because I simply never played them. I simply don't know these heroes. Your argument is simply bollocks. You can know Soviet units, you can know the army, you can have general idea how to play them but nothing will beat pure experience of playing and using the army yourself. That's the basics of learning RTS. You have to play every faction to simply know them. You can have your favorite one but you have to play the all to stay competitive. I am sure EVERYONE on this forum who takes RTS seriously and have some basic understanding of the genre will agree with me.
