I dont get how this is revolved around "Soloing" now.

It states they are decreasing the bonus you get from leve linking, but increasing the maximum links you can have, atm its 4 until SP bonus stops, now you need more?!?

How does that promote solo? Or even make it solo like content, if you need more people than before to be able to get the good SP.

So backwards, unless im missing something here.
