For the longest time wormholes have been untouched by CCP. It is widely accepted that wormhole space is one of the few parts of EVE which do not require direct iteration on as it Just Works™. That said, it was nice to see CCP sending some love our way with a variety of changes to shake w-space up a little. Unfortunately the largely welcome changes listed in the dev blog were overshadowed by the horrific addition of mass-based spawn distance when jumping through a wormhole
The suggestion is to have ships with larger mass spawn further away from the wormhole they jumped through. The poorly formed reasoning behind this is that slowing down hole rolling will make it more risky for groups to isolate themselves from the rest of New Eden. While this is a laudable design goal there doesn't appear to have been any deep thought applied to whether the implementation actually achieves the goal (hint: it doesn't).
In any given wormhole system there are two sources for connections. The first is the static connection which residents have control over. The second is incoming wormholes which residents have no control over. At any given moment in EVE there are people rolling their static to close it so they can run PvE sites and there are also people rolling their static to catch people running PvE sites. CCP is directly targeting the former group. It is not possible, however, to only target one group with changes to the hole rolling mechanics. Players who seek to isolate themselves will only roll one or two holes in an evening. Active corps rolling for content roll many more holes than that. The latter group is affected more due to this change for the simple reason that they are rolling more.
When we have a fleet running we are looking for people to shoot or sites to run. We're not too fussy but will pick shooting people first any day. If our static connection has nobody there we roll it. With this change CCP are not making it riskier to roll wormholes, instead they are making it slower. As it is slower there will be less K162 holes generated in a given evening. As K162s are the only source of finding isolationist who have closed their static holes the net reality of this change is that isolating yourself becomes easier.
I find it hard to believe CCP don't realise. They have a 27 page (and counting) threadnaught which hopefully opens their eyes to how bad an idea this is. If CCP go ahead with this change it will be clear that, despite their statement that they want to make hole rolling riskier, what CCP truly want is to make life easier for corps who want to isolate themselves.
