WMB2x90 Anti-Kaiju Missile Launcher

Hey guys and girls, just wondered in the original film why Striker's missiles took way longer to fire against Otachi than they did against Mutavore? Also, during the Drift test with Raleigh and Mako, why did Gipsy Danger's 1-19 plasma caster take way longer to shoot? Were they overcharging it like Raleigh did against Knifehead after Yancy died?

The main one with Gipsy Danger as well as the one with Gipsy alongside Cherno and Striker is cool too. Do you guys like the weapons posters? E.g. the labels on the jaegers and them being somewhat demonstrated; such as Striker's blades or Cherno's incinerator Turbines?
