If instead of building a panic puma, you build panzerschrecks or even a second pak to stall until t3 hits, you'd have a much stronger mid to late game. It's bad because most of the time people use it they would have been better off not using it. Does that make sense? Also 9/10 players forget to tech and float 300 billion fuel after they get their panic puma and command tank combo out, but that's just bad RTS fundamentals at work.
The only time a panic puma makes ANY sense is if you are losing really, really hard and T3 isn't an option anymore. If you're sitting on three strat points and +7 fuel, fine.
So you think the majority of ESL players that choose Ostheer just don't know what they are doing then. Alright. They clearly never thought about getting Schrecks and forget to tech up. All 35% of games played was just a total noob in control.
