I had recently done this cut scene as well on my shadower, comes up with a video can not be played error as well had to press esc key to allow me to continue onward.
The scenes before are like, ah cool something big is gonna happen. "Video can not be played" Well that's a bit of let down type of feeling reminds me of having to watch kain video on youtube afterwards to see what happened when it first came out for the second job advancement.
For the green node stones, once you had double clicked them, they'll up end up in the menu at the bottom with all the other node stones. You can use them on any node that has been set and they give a large chunk of exp for that node. Just move the mouse over the node from the ones that are set on the top that you want to increase then right click on it and click on enhance the green exp node should appear as a choice to use as exp fodder for that node your increasing.
A few things I can recommend that can also help to get some extra damage as well, is to get the totems from the after lands quest line and also the medal from masteria from time quest line. Other suggestions might be to try to complete the mushroom shrine quest line for the cape until you can get something better.
I just don't see why the upgrade system is not just a low number of reward points on both server types for the special upgrade cards like 400 reward points or something like that and allow something like 5 or 8 cards per month for reward points and if you wanted to you could spend nx to get more cards if you wanted to, that way both servers get a win instead of a low ball cash grab.
