That's not OKW players' fault. It's the faction. Cool units, bad design. In order to win, what you will use? A tactic that requires alot of micro and fragile units? No, you will blob as much as possible, you will rather wait for stronger units, while trying to hold the line, etc. This is why blobbing is so viable for OKW and life saving. What else can you do? (well, in the past, you actualy could, but the latest changes, issued to "balance" OKW made it even more depending on blobbing and the strongest units than before). Here's your answer.
I agree, and I also believe that blobbing is a valid tactic. But I think you can still blob and win as OKW, watch Paul's stream, but it's much riskier now.
What I meant was coz OKW blob was so good you could get good win percentages. Thus you were playing with higher ranked, maybe better skilled, Sov/US players, and winning. Now OKW isn't as potent, these players are finding it harder to win.
