No. You've expressly forbidden me from using DM arbitration, far more than twice. Far more. The consequence of your own declaration is that everyone is visible at all times without error or exception, provided they are not in heavy obscurement / total cover. By enforcing the lack of DM arbitration so fervently, you've created a situation of blatantly superhuman eyeballs. Constantly.No, Im expressly allowing it. Have said so twice.
I just assert your base reading of the rules is wrong, and I disagree with your arbitration of those rules which results in absurdities like a creature in heavy rain being hidden., despite being unable to hide in heavy rain, and being stared straight at, and despite the rules stating 'if you come out of hiding and approach a creature, it sees you'.
