Army Attack ripped off ATTACK On Titan

Ok, so, Army Attack ripped off Attack On Titan, and you might be thinking, "But Army Attack came out before Attack On Titan! In 2011!" Well true, but ever since RockYou bought it in 2014/2015, they added units like the Sie sind das essen nein und wir sind die Jaeger, and the Levi Ackerman, I MEAN the Titan Buster, and Attack on Titan came out in 2013, and both series have 'Attack' in the title, not to mention the fact that one new buyable unit that was added is a giant mechanized suit of armor, so, are we the prey? No! We are the hunters!
