Krasue Should Work Like Oni (Strong Power, Have to Work For It)
If we look at Oni he was a very strong chase power, which can down even faster than Krasue's can. However his power is balanced because he has to work for it in an M1 Scenario.
If Krause had to work harder to infect survivors, then her power could also be balanced, that being a 120% move speed killer + big lunge.
Regurgitate should have a longer cooldown before you can m1 after and should have more slow to it.
Regurgitate should have a longer cooldown it's self before you can use it again
Remove the auto aim entirely from Regurgitate or at LEAST heavily reduce it
With this change the main part of the length of a survivors chase will be from the infection mechanic and then she can have a quicker chase in head form keeping it as it currently is.
This would be the easiest band aid fix I believe for Krasue without having to put in to many changes or completely rework her entire kit.
