ST, changes to test ships

[GOMBEE8626]

British battleship Thunderer, tier X:

• Main battery guns reload time lowered from 30 to 26 s;
• Sigma lowered from 2.0 to 1.9;
• Lowered the size of the dispersion ellipse.

Thunderer has a relatively weak armor scheme and not the best Repair party, her main strength is her guns. But testing showed that they were not efficient enough. 

American battleship Ohio, tier X:

• Main battery guns reload time increased from 26 to 30 s;
• Sigma increased from 1.9 to 2.0;
• Increased the size of the dispersion ellipse;
• Amount of hit points restored per second by Repair party is lowered from 0.66% to 0.5% of maximum hit points.

Thanks to effective secondaries and good guns, Ohio was too effective at all distances. The guns parameters were changed to keep the ship strong in close and medium range, but lowering the overall efficiency. Moreover, Repair party had too big of an impact on the overall survivability of the ship.

Italian researchable cruisers

• Removed the damage limit of semi-armor-piercing for shells of caliber of 283 mm and lower against destroyers;
• Improved ricochet angles of semi-armor-piercing shells from 60-85 to 80-85;
• Changed the basic firing range of main caliber guns:
  • Taranto, tier III: increased from 9.6 to 10.34 km;
  • Alberto di Guissano, tier IV: lowered from 14.14 to 13.51 km;
  • Trento, tier VI: lowered from 15.37 to 14.65 km;
  • Zara, tier VII: increased from 14.32 to 14.65 km;
  • Amalfi, tier VIII: increased from 13.95 to 14.68 km;
  • Brindisi, tier IX: increased from 15.21 to 15.57 km.
• Venezia, tier X: improved firing angles for the second turret by 19 degrees to both sides.

Semi-armor-piercing shells are an intermediate between AP and HE shells: AP deals good damage when hitting citadel, HE does stable but relatively low damage and can causes fires. SAP shells should deal good stable non-citadel damage, but due to the ricochet angles they were not effective. Also, due to the limit on damage against destroyers, this cruisers were weak against this class, so the limit was removed.

The changes to the firing range will build the progress logically from tier to tier.
