It's not so funny, sure. Perhaps, you in developing of a tank for years, processing some Shadow for years. And -- ho! The game mechanics is changed. "Stealthy".
PoW is a Nate's game. More than the game of stable managers. It's sad, it has a reasons. But it's true.
For me it's just a Nate's mistake. Because i feel it, i feel the truth is more powerful weapon than the "stealth". But it's only my opinion.
