2nd iteration of the double cannon tanks are here, and our friends at WG thought that the ST-II was a tiny touch too good, so decided to nerf it.
• Gun reload time (1/2): 11.25 / 11.25 sec. (did not change, just here for comparison)
• Preparation time of a volley shot: 2.5 sec. (did not change)
• Recharge lock time: from 5 to 3 seconds.
• Barrel change time (in order to fire a shell from other barrel): from 3 to 5.5 seconds.
