This is what I am afraid of. Without reducing the current repair requirements by a factor of 100, we're soon going to run out of stations in the bubble, with system after system attacked, and every week more stations thrown into damage, and 100s of systems in endless "incursion" states, because the requirements are simply too high.
Meanwhile, only those who actually care about the system or station will get involved in repairs, so repairs must be doable by 2-5 CMDRs in 4-5 days of solid grinding, or it will just cascade and cascade. Add to this the increased work in maintaining one's faction due to the new BGS mechanics, and I can see this turn off the BGS players who care enough about a particular system to even attempt to repair it...
I see just one bright spot here (should the requirements not be changed): it will protect systems from bots and other attackers, if it means that the incursion state blocks any conflict states, so it will have a defensive aspect. However, if that's the case, nothing will ever get repaired...
