I added all these nodes to my config file
*SNIP*
but I still cannot sync. I'm connected to ten nodes so it doesn't look like a node issue. Mintcoin is running 50% of my cpu power but remaining blocks to sync are even growing (are 5581 now) because my wallet is not confirming anything
addnodes in the conf file are largely un-needed UNLESS you somehow cannot initiate DNS queries from your computer (very rare, and you'd know if this was the case).
Your wallet is likely verifying a large chunk of received blocks before continuing to download new ones. During this time it'll see that new blocks are being created, hence the increase in number of blocks to download.
