Kinship should be slightly changed and made basekit.
The idea is good. 30'ish extra seconds on hook when conditions are met, but triggering when another survivor is in range and only on the 2nd hook state? Weird conditions and too niche. Triggering when the killer is in range instead and on both hook states? Much better and would make camping more detrimental.
Could be tweaked further for workarounds but I don't think anyone would argue that we've needed an anti-camp measure for a while now. Especially now that gens take longer.
