The kind that dies as soon as they're out of the clouds? Everyone will be on an equal footing. I don't understand why they ought to be kept out when they're so immersive and add relatively so much tactical variety.
Lemme give a story.. We were in some scenario, FSO or CAP or something, back when Wotan still had his JG2. We were in Me262s, coming back either from the first or second stint, rtb'ing. We had failed to find some Il2s... The rtb field was overcast..

You can guess what happened that had us utterly embarassed in the tower.
Yeah, I think clouds are great. Would definitely bring as much good as bad. No more strato bombers. A new type of "NOE" dweebery.. But all in all I think it's a positive addition.
