Pro-Tip: Did I mention specials are more aggressive? They can run 10% faster (except Tank), and they have pretty much no delays with their attack. Common infected also run 10% faster too.
Pro-Tip: Normally when a Boomer finds its self seen by a survivor for 1 second, it is told to hide/take cover. On my server, I raised this time to 90 seconds meaning Boomer will simply charge in and will immediately barf on you once in range.
