British cruiser Exeter, tier V.
Main battery reload increased from 12 to 15 seconds;
Removed the consumable "Smoke Generator".
Exeter's reload is increased to the value of another heavy cruiser of this tier - Furutaka.
"Smoke Generator" is removed, because in the presence "Repair party" and guns with the caliber of 203 mm, this consumable gives an excessive advantage in battle.
