Sorry for any confusion this may have caused!
Clown buff idea
First of all buff the percentages of slow from gas from 15% to 20%.
The next is if survivor stay in the gas cloud , the longer he stay the percentages will increase from 20% to 30% max.
Increase his bottle by 1 more. Clown sometimes have a situation where he are almost to catch survivor but he can't since need to reload his bottles.
Next are . Survivor what are working on a generator sometimes they will get a clown face on a screen (like's from a doctor madness) they will blow up generator by 5% more and can't work on them by next 7 seconds (percentages and time for balance)
I think a problem clown is bottles sometimes makes him slower than slowing survivor so increased percentages are necessary. 1 extra bottle. And gen control by stopping someone while clown can't reach them.
