As I and many others have already posted, the lightning storm is too powerful and other than sitting in your base and being able to cast darkness spells, other players can pretty much one or three shot your base now (no matter how large/strong).
Not sure if already suggested but one idea I came up with (other than nerfing the storms which probably needs to happen…) is to somehow allow sorcerer thralls, in your base, to reduce the damage. The more powerful the sorcerer, the more damage it negates (possibly by having a new type of bench to put it in). Maybe even limit the number of defenses that said sorcerer provides?
At least it would give a reason to capture T4 sorcerers…
