I've just updated the planner.
I'm hoping that the defender/guardian information was just glitched and that this new version will fix it.
If somebody else could check that would be great (I've tried it here & it seems to be working, but then I never had an issue in the first place).
There is also one modification to the program.
All classes have a skill guide on the forums with comments about the skills and whether they are useful etc.
All of these comments are now included in the planner.
Where the skill is listed, if you hover your mouse over it you should see the comment appear in a tool tip.
If you don't see it appear immediately, try hovering somewhere else - the skill icons are usually a good place
