New CoH vs Old CoH numbers
Hello, DBD Community! The Reaper is here to show you the numbers so you don't have to.
This is more complex than some people might think due to how CoH is coded. You see, self-heals share identical coding with Self-Care, which explains why it even had the text "self-care" when it was originally released. So, you do get the 50% penalty, but it also benefits from CoH heal speed bonus to counter it.
Old with Mangled: 20
New with Mangled: 22.5
Much easier to calculate since there's no 50% penalty to keep track of.
Old with Mangled: 10
New with Mangled: 11.25
CoH + Emergency Medkit = 7.1 seconds vs the old 6.4 seconds.
CoH + Emergency + Botany = 6.2 vs 5.65
So really, not much has changed. Except stacking Medkit charges are going to be better than using an Emergency medkit for ultra-fast heals, but I'd argue that was already the case.
Interestingly, CoH is as efficient as Self-Care (discounting totem time) with blessing + healing adding up to 32 seconds. Insert obligatory "Self-Care is not a bad perk" here.
Edit: minor corrections due to Mangled weirdness
Edit 2: I originally rounded the numbers to the nearest one, but to be a little more accurate, I instead rounded to the nearest hundredth. You're welcome.
