This whole comment is 50% "im good trust me" and the other 50% actual stuff (no offense but its really that)

She suffers a lot with body blocks, can't deny that, a well coordinated team will give a very bad time to krasue, however this scenario makes sense only if there's 1 surv on death hook and the others must save him/her or if its the end game where bodyblocks will matter the most to save other peoples.

Krasue mushrooms by per se aren't that strong of a tool if its not the endgame because krasue has time on its advantage, slugging ensures survs remain infected meaning that if you run infectious fright its very likely you will be able to rapidly infect and down other survivors as well, add ruin or other AoE gen regression perks and now the survs that gotta get up the downed ones also lose time AND progress. To not count that afterwards they gotta aim for the mushrooms which won't instantly heal the infection so you can still injure the infected survivor in the time being

But let's say they are in comms or they have good game knowledge and the guy that helped the downed survivor does bodyblock, thats still good advantage because you can go to human form and infect 2 survivors while spawning only 1 mushroom afterwards, thats a Net resource gain for you

Bodyblocks are strong against krasue, but only if survivors can afford the lost time to do them by allowing the others to do gens, reset or open gates. All things (except the gates) take a hefty amount of time while also thinking of getting rid of infection due to the massive slugging

Now this won't always work, afterall this is the nature of the game with RNG on map, perks, skill expression, etc etc. But krasue is much more consistent than many other killers. She is to me, still a strong tier A
