We've encountered two issues with anti-air defense mechanics after the 0.8.0.1 hotfix:
Large damage spikes from AA explosions in tier VIII and above (this is a bug, the damage increase should be proportional)
Continuous DPS on several ships/tiers needs further adjusting (mostly toning down slightly);
We're already working on resolving both issues, but to avoid any further issue, we plan to spend a couple of days double-checking everything and preparing the update.
We currently plan to release this hotfix early next week..
We apologize for the inconvenience and thank you for your patience.
The World of Warships Team.
