Having been a victim of the biggest random event, so far, in GW4 (African Volcano) the impact for me was Punctuality reduced to 13% which in turn led to 25% being wiped off CI.
The only action that I could take (as far as I can see) was to increase marketing to restore CI, which I'm still paying for.
You can't plan for these events as you would do in real life, and you can't implement contingency plans quickly as you would in real life. If you are away from the game for 24 hours (I like a good drink every now & again) a game month can pass before you even know that the event happened. Realistically does the flying public blame an airline for an Act of God & mentally mark their image down by 25%?
For me this is just a random hit on profits, should you be "unlucky", and therefore adds nothing. It certainly doesn't help the game's credentials as a educational tool.
Feeling just a little sabotaged at the moment, as I suspect the few operating out of Africa are.
How about letting me insure against more Random Events?
