You've said in the patch notes you've "re-balanced" heat stroke...
The maps been out only a few weeks, you've already made it easier making irrigation water safe to drink. The challenge of finding water encouraged co-operation, seeking out chlorine or boiling water and giving away your location. It's as good as having water wells running through the entire map now on top of rebuilt wells and water trucks, the only unsafe water is in bottles or the few ponds/lakes that there are. It's not as if pop cans and other drinks are not easy to find either.
Heat stroke was fine as is, other than the icon being bugged, it was manageable.
Don't tame the vision because of a vocal minority.
May as well just spawn everyone in with 6 bottles of water, a plate and a DMR.
