I love the summer event as well, and the generosity behind it. Thank you!
My suggestion is: wouldn't be really interesting to have some "extreme modifier" events? Like all ambient temps increase or decrease by 25%? Or armor is increased/decreased by 25% for all mechs, etc... ?
I don't think you'd want to do this often, as it totally breaks the game, but once in a while it might be really fun.

Thanks again.
