A new EARLY GAME slow down perk

Ok, we won't have Ruin anymore as an early game slow down, leaving us with just Corrupt Intervention, so here's my suggestion for a new perk:

Isolation

While repairing a generator alone, you suffer a 28/32/36% penalty to repair speed. For every generator completed, the penalty is reduced by 7/8/9%.

(Note: current numbers are just a suggestion, point is that the penalty will come to 0 once only one generator remains, and the more generators the team completes, the lesser the impact of the perk)

Rationale

The most insidious gen rushing happens when survivors complete generators alone, since they don't suffer any penalty from it. This means that now that Ruin is gone, after the killer's first chase there's a significant probability that a couple of generators could already be completed, if people split up properly (for the sake of discussion, I'm not considering toolboxes or perks like Prove Thy Self).

With this perk survivors are still able to complete generators exactly as before if they stick together, but this also means that killers have a higher probability to pressure multiple survivors once they identify their general location (plus it would synergise very well with Discordance, an arguably underused and underwhelming perk as of right now). However, if they decide to split up and be immersed they'll suffer a very big penalty in the early to mid game, giving more time for the killers to setup / complete their very first chases.

Of course this penalty needs to fade away once the game goes on, otherwise gens could become too difficult to complete due to their location / survivors deaths / Dying Light or other slow down perks.

Is this in any way interesting?
