I don’t think it will be. Most new players aren’t immediately going to nullsec to start making isk. If they do go, it’s usually to PvP, and the groups they will be joining all have enough space to provide plenty of room for them to grow. The rest will still be in highsec running missions, happily not impacted at all by this change.
This change has a much larger impact on veteran players, especially those using expensive ships and counting on umbrellas and intel networks to keep their space safe. They’re the ones who will have to move around the most to maximize their income. That’s not something they had to do before, so they’re going to hate it. Newer players won’t know the difference.
